Moved schema validator into the schema module
- This is a really specific piece of code related to validating models against our internal schema.js format
- This doesn't make sense without a schema.js file
- It does depend on the internal validator and validate tools - but those are used elsewhere too, and can reasonably be moved out of the codebase
- I don't see schema.js moving out of the codebase any time soon. We can move the validator but it would be a class that requires schema via DI
- For now my focus is on getting the data/validation tooling separated and making clear sense
- Improving data/schema can come later :)

Split validation index into separate files
- The data/validation module is made up of several loosely related things with lots of dependencies
- Separating out the various components makes it possible to see what's what, and importantly what has complex dependencies
- validator + validate probably go togetheri in an external module, the other two files should probably have their own homes in related areas of ghost e.g. schema -> data/schema/validate.js

Added posts_meta.feature_image_{alt,caption} columns (#13030)
refs https://github.com/TryGhost/Team/issues/770

We want post feature image functionality to better match what's available inside the editor, to do that we'll need somewhere to store alt and caption meta data. `posts_meta` chosen because even though we want to make this generic for other tables in the future those tables also have a `feature_image` (or closely related) field.

- updated schema with new columns
- added migration to create columns
- cleaned new columns from API output
  - not output on v2/v3
  - conditionally output on v4/canary output based on labs flag
- bumped `@tryghost/admin-api-schema` to allow new columns through in canary API requests
  - silently clean properties from input when labs flag is disabled
  - updated acceptance tests so they fail if `admin-api-schema` is not letting the new fields through

Swapped to American English spellings
- Traditionally all of Ghost's public-facing text was written in British English
 - We're changing that to US English because that's more common
 - US English should also be used in code e.g. properties are called color not colour
 - most of these changes are in comments, but I've changed them so that we have US English in front of us always
 - fixed a few other typos I noticed whilst there

49ba26373d 🏗 Added "labs" setting enabling feature flags
refs https://github.com/TryGhost/Team/issues/757
refs https://github.com/TryGhost/Team/issues/332
refs ea6d656457

- We have a need a quick way to add features behind flags. The old way of "labs" is the quickest way to achieve this. It has ready tooling around it and well understood pitfalls. This change reintroduces "labs" group & key in settings table in the same shape it used to be (see reffed commit)
- Next step will be introducing very basic guard rails to protect from pitfalls previous implementation of "labs" had. This will include an allowlist based input validation for lab's object's data
-  The labs being an "object" type is an EXCEPTION. Even though it's an antipattern we aim to move away from, for now it's the lowest impact solution that will unblock the use of flags in the system. A proper solution will come at some point.

Added {monthly,yearly}_price columns to products
refs https://github.com/TryGhost/Team/issues/710
refs https://github.com/TryGhost/Team/issues/725

Products will now have a single monthly and yearly price which will be
used throughout Themes, Portal & Admin. These columns will be used to
track the current prices for each of them, and will update anytime we
change the pricing of a product.

Due to a circular table dependency we have not added a foreign key
constraint to the new columns, this will be handled at a later date. It
is tracked in issue 725 references above

Since backend now allows multiple prices but we want the prices to be currently limited to monthly/yearly on UI, we need new settings to store the current monthly/yearly price by the site owner.

6106d1fdc4 Updated active column type from boolean -> bool
no-issue

Our base model will only automatically convert numbers to booleans if
the type is 'bool' - however this column was incorrectly added with a
type of 'boolean'. Lucklily - knex with both MySQL & SQLite3 will add
a column with the same type for both of these, so no migration is needed
to fix it.

b35f060bef Added settings for members 'free' price
refs https://github.com/TryGhost/Team/issues/637

The "free" price - when Members signup without using Stripe, should have
a name and description, so that it can be displayed in Portal in a
similar way to paid price's. As there is only ever one, and it is not a
fully fledged price, a setting makes more sense than a dedicated db
table.

a138586c83 Updated stripe_plans & portal_plans settings
refs https://github.com/TryGhost/Team/issues/586

We are no longer using the `stripe_plans` setting, instead we are using
the `stripe_prices` database table. However, we must keep the setting as
the migration from the setting to the database is not done as a standard
migration, but in code. This means our code has to still read and pass
the setting because we will never know if the migration in code has run
yet.

The `portal_plans` setting has been updated to only include 'free' by
default, because the setting must include id's now rather than names.

Removed unique constraint from Product names (#12928)
refs https://github.com/TryGhost/Team/issues/586

A discussion in the Members team resulted in us determining that we do
not need to enforce unique names for Products. Stripe does not enforce
uniqueness for their Products, and we feel it's not necessary for us to.

Added ability to send a newsletter to members with a certain label or product (#12932)
refs https://github.com/TryGhost/Team/issues/581
refs https://github.com/TryGhost/Team/issues/582

When publishing a post via the API it was possible to send it using `?email_recipient_filter=all/free/paid` which allowed you to send to members only based on their payment status which is quite limiting for some sites.

This PR updates the `?email_recipient_filter` query param to support Ghost's `?filter` param syntax which enables more specific recipient lists, eg:

`?email_recipient_filter=status:free` = free members only
`?email_recipient_filter=status:paid` = paid members only
`?email_recipient_filter=label:vip` = members that have the `vip` label attached
`?email_recipient_filter=status:paid,label:vip` = paid members and members that have the `vip` label attached

The older `free/paid` values are still supported by the API for backwards compatibility.

- updates `Post` and `Email` models to transform legacy `free` and `paid` values to their NQL equivalents on read/write
  - lets us not worry about supporting legacy values elsewhere in the code
  - cleanup migration to transform all rows slated for 5.0
- removes schema and API `isIn` validations for recipient filters so allow free-form filters
- updates posts API input serializers to transform `free` and `paid` values in the `?email_recipient_filter` param to their NQL equivalents for backwards compatibility
- updates Post API controllers `edit` methods to run a query using the supplied filter to verify that it's valid
- updates `mega` service to use the filter directly when selecting recipients

Added default email recipients settings (#12925)
refs https://github.com/TryGhost/Team/issues/496

We want to give more control over the default selection of email recipients when publishing a post, to do that we need somewhere to store those settings. These settings are site-wide and intended for use by admins to control the default editor behaviour for all staff users. They _do not_ control API behaviour, if you want to send email when publishing via the API it's still necessary to explicitly opt in to that using the `?email_recipients_filter=` query param.

- new `editor` settings group to indicate that these settings only affect the UI rather than the API
- `editor_default_email_recipients` controls overall behaviour, string/enum with these allowed values:
  - `'disabled'`: no option to send email is shown in the editor's publishing dropdown
  - `'visibility'`: (default) selected member segment is dynamic and matches the post visibility filter
  - `'filter'`: specific member filter defined in `editor_default_email_recipients_filter` setting
- `editor_default_email_recipients_filter` is an NQL string for selecting members, used when `editor_default_email_recipients` is set to `'filter'`
  - default value is `'all'`
  - the segment string can be any valid NQL filter with the additional special-case values of `'all'` and `'none'`

- i18n should be a shared module for now so it can be used everywhere until we figure out something better

Added Default Product fixture (#12892)
refs https://github.com/TryGhost/Team/issues/619

As part of the Custom Products work, we are linking members to products
when updating their subscriptions. This requires that we have at least
one product in the database. For existing sites that are using Members
this is handled by the v4.3 03 migration. But for new sites we must
include a fixture.

Also fixes the tests to not reply on the order of the fixtures

Migrated members_allow_free_signup setting to members_signup_access (#12886)
refs https://github.com/TryGhost/Team/issues/579

Currently the members signup setting is explicitly yes/no to allowing free members signup, with the implication that when set to "no" members is still active but members have to be created via Stripe or the admin API.

This change renames the setting and changes its type to allow more than a binary option.

- migration to create/update the new setting based on the old value
  - free signup = "all", no free signup = "invite"; matches the current UI for this setting
- rename setting everywhere it's used/tested against
- modify `getAllowSelfSignup()` used to configure members packages to only return `true` when the new setting is set to `'all'` to match behaviour to the older setting
- update importer to rename the setting when importing from an older Ghost version

- Add the products table, so that we can store Products in Ghost

Populating the tables allows us to transition from the current system, which does not care about products, into the
new system, where Products are used to group members. The intention is that all existing paid members have the
same product

💥 Reduced default exports content for DB APIs (#12818)
refs https://github.com/TryGhost/Team/issues/555

- Export files included a lot of data which was not used in the importer, for example: members,  labels, migrations and many more. This lead to a lot of clutter in the import files and made it hard to reason about their purpose.
- The main purpose of exports - is to export importable resources. These are posts, tags, and users. The rest of data like members or migrations either have their own importer (like CSV importer for members) or does not and should not have any ways to be imported.
- These changes are in now way complete. It's a first step towards resource-based exports which could be properly versioned in the future on API level and not be a mirror of the DB structure.
- This is sort of a breaking change. But we are doing it because: (1) its an internal API that should not be used by external clients, (2) there was no public contract to have this API stable at any point, (3) we really need to get back the control over export files structure and size
- In case an external client was dependent on some structure of the exported json file they can still pass in ALL of previously exported data by passing table names in `include` query parameter.

Note on accent color:

This commit changes the default accent colour again.

The intention is that new sites should get #FF1A75 (pink) as their default.
Any existing sites that do not have an accent colour set yet, should get #15171A (black) on upgrading to 4.0.

These are different as they are different experinces. Fresh sites will be guided to pick a color, so
a bright color is more visible and helps to see what can be done, whilst existing sites get a muted
black, that should be a sensible fall back color.

Added default value to accent_color setting (#12743)
refs TryGhost/Team#535

We want to ensure that a site will always have a default value of
`'#15171A'` for the accent_color setting.

Since the boot process changed we have three cases to account for:

1. Setting does not exist
2. Setting exists with no value
3. Setting exists with a value

It is only in the case of 2. that we want the migration to update the
database with a default value.

In the case of 3. the site owner has already set a value, which we do
not want to override.

In the case of 1. the setting will be created (and populated with
default value) from the default-settings.json file, by the
populateDefaults method called from the settings service

We also update the accent_color setting to include a non-empty
validation, to ensure that the setting will always have a value, as
sites before 4.x may have an empty accent_color, we must update the
importer to set the default value if one is not present. Otherwise we
would run into validation errors and even if we didn't would have an
invalid database state.

e30b9735fa Added staff user limit
refs: https://github.com/TryGhost/Team/issues/510

- In the case that host config is provided, keep staff users within the limiti
- The definition of a staff user is a user with a role other than Contributor, and whose status is not inactive
   - Contributors don't count
   - Suspended (status inactive) users don't count
   - Locked users DO count
   - Invited users DO count
- You can't invite more staff users whilst there are pending invites
- You can't unsuspend a user, or change the role on a user in such a way as will take you over your limit
- You can't import staff users - all imported users are automatically set to Contributors
- As part of this work, we are changing the default Ghost user to a Contributor otherwise it uses up a staff user

Note: there is one known active bug with this commit.
- Assume you have one remaining user within your limit. You send an invite, this works.
- You cannot "resend" that invite, it will think you're sending a new invite and hit the limit
- You must "revoke" that invite first, and create a new one
- This bug exists because the resend function uses the add endpoint & does a delete+add, but this hits the permission check before the delete

Updated members_status_events table (#12647)
refs https://github.com/TryGhost/Ghost/issues/12602

* Updated members_status_events table

By replacing the `status` column with a `from_status` and `to_status`
column, we are able to track the changes between multiple statuses
easier, and accumulate the data. e.g. the delta of paid members in a
given time range is the sum of the `to_status` columns set to 'paid'
minus the sum of the `from_status` columns set to 'paid' within that
time range

* Updated MEGA to handle addition of 'comped' status

With the addition of the 'comped' status, we need to ensure that MEGA
will still send emails to the correct recipients. I've opted to use an
"inverse" filter, as that is the intention of the free/paid split in
MEGA - as far as MEGA is concerned, "free" is the opposite of "paid"

* Updated customQuery for MemberStatusEvent

With the `status` column replaced with `from_status` and `to_status`
this allows us to fix and update the customQuery to correctly accumulate
the data into deltas over time, broken down by day.

* Populated members_status_events table

As the table will be used to generate deltas, we need to backfill the
data so that existing sites will be able to sum up the deltas and
calculate correct data.

The assumptions used in backfilling is that a Member's current status,
is their only status.

12c28fe66e 🏗 Updated "slack" setting into "slack_{url,username}"
refs https://github.com/TryGhost/Ghost/issues/10318

- Object format used in previous "slack" setting was considered an
anti-pattern. Flag structure of separate slack_url and slack_username
values was extracted out of the "slack" JSON.

Updated members_email_change_events to store previous email (#12641)
refs https://github.com/TryGhost/Ghost/issues/12602

As we only want to add events for when an email is changed, we need to store the previous email if we want a complete log of all emails for a member
