- Previous blocklist approach was resulting in adding every single new table into an export automatically. Which creates possibility to leak sensitive data if not used porperly. Allowlist approach gives better control over what is exported, makes this information explicit, and version-control friendlier
* refactored `core/frontend/apps` to destructure common imports
* refactored `core/frontend/services/{apps, redirects, routing}` to destructure common imports
* refactored `core/frontend/services/settings` to destructure common imports
* refactored remaining `core/frontend/services` to destructure common imports
* refactored `core/server/adapters` to destructure common imports
* refactored `core/server/data/{db, exporter, schema, validation}` to destructure common imports
* refactored `core/server/data/importer` to destructure common imports
* refactored `core/server/models/{base, plugins, relations}` to destructure common imports

* refactored remaining `core/server/api/v2` to destructure common imports
* refactored `core/frontend/meta` to destructure common imports
* fixed some tests referencing `common.errors` instead of `@tryghost/errors`
- Not all of them need to be updated; only updating the ones that are
causing failures
* fixed errors import being shadowed by local scope
* Simplified db controller permissions options
The existing objects were confusing because they did the same thing as
setting permissions to true, but gave the impressions that something
special was happening/required.
* Added DB Backup Integration Role
This will allow us to assign certain api_keys this role, in order to
automate db backups
* Allowed admin api_keys to have configurable roles
This will allow keys for the admin api to do customised things such as db export
* Added ghost-backup integration to fixtures
* Added migrations for DB Backup Integration and role
