On `main`, currently, haddock generation is broken, due to some unrecognized comments. This PR fixes this, and changes our `build_oss_server` CI job to ensure that future PRs do not break haddock.

This commit applies ormolu to the whole Haskell code base by running `make format`.
For in-flight branches, simply merging changes from `main` will result in merge conflicts.
To avoid this, update your branch using the following instructions. Replace `<format-commit>`
by the hash of *this* commit.
$ git checkout my-feature-branch
$ git merge <format-commit>^ # and resolve conflicts normally
$ make format
$ git commit -a -m "reformat with ormolu"
$ git merge -s ours post-ormolu

GitOrigin-RevId: 75049f5c12f430c615eafb4c6b8e83e371e01c8e
### Description
- sets up a Makefile target for running ormolu to format and check source code
- updates CI to run ormolu instead of stylish-haskell (and to check instead of format actively)
Compare #1679.
Here's the plan for merging this:
1. merge this PR; at this point, all PRs will fail CI unless they have the `ignore-server-format-checks` label set
2. merge follow-up PR #2404 that does nothing but actually reformats the codebase
3. tag the merge commit as `post-ormolu` (also on `graphql-engine`, for the benefits of community contributors)
4. provide the following script to any devs in order to update their branches:
```
$ git checkout my-feature-branch
$ git merge post-ormolu^
$ make format
$ git commit -a -m "reformat with ormolu"
$ git merge -s ours post-ormolu
```
(I'll put this in the commit message)

### Description
This PR improves error messages in our metadata API by displaying a message with the name of the failing command and a link to our documentation. Furthermore, it harmonizes our internal uses of `withObject`, to respect the convention of using the Haskell type name, now that the Aeson error message is displayed as an "internal error message".

### Description

While adding [insert mutation schema parser for MSSQL backend](https://github.com/hasura/graphql-engine-mono/pull/2141) I also included [identity](https://en.wikipedia.org/wiki/Identity_column) notion to table columns across all backends. In MSSQL we cannot insert any value (even `DEFAULT` expression) into Identity columns. This behavior of identity columns is not same in Postgres as we can insert values. This PR drops the notion of identity in the column info. The context of identity columns for MSSQL is carried in `ExtraTableMetadata` type.

Some of our use of CPP causes trouble for ormolu, compare https://github.com/tweag/ormolu/issues/774.
Specifically, for understandable reasons, it can't deal well with `#ifdef` use that is not at the top-level.
This PR removes the problematic usage in ways that I hope are also a net non-loss regardless of helping
out ormolu (or other tooling).
- The default value for enabled APIs moves to the top level, next to the command line help, so
they'll stay in sync more easily.
- All the CPP around using `assertNFHere` is moved to one module.

## Description
Almost all our data structures use strictness annotations, following [our styleguide's principle](https://github.com/hasura/graphql-engine/blob/master/server/STYLE.md#dealing-with-laziness) of "by default, use strict data types and lazy functions". The very few cases where we actually need laziness were already explicitly labelled as lazy with the `~` prefix operator.
This PR simply globally enables `StrictData`, allowing us to express records without `!()` on every field, but makes no attempt at cleaning existing code.

### Description
We always build a subscription root, even when there was no possible fields. This breaks some third party clients, as the spec does not allow empty types in the schema. This PR fixes this by changing the `buildSubscriptionParser` helper to return a `Maybe` value, and harmonizes / cleans places where we build the subscription root.

This is a follow-up to #1959.
Today, I spent a while in review figuring out that a harmless PR change didn't do anything,
because it was moving from a `runLazy...` to something without the `Lazy`. So let's get
that source of confusion removed.
This should be a bit easier to review commit by commit, since some of the functions had
confusing names. (E.g. there was a misnamed `Migrate.Internal.runTx` before.)
The change should be a no-op.

### Description
During the PDV refactor that led to 2.0, we broke an undocumented and untested semantic of inserts: accepting _explicit_ null values in nested object inserts.
In short: in the schema, we often distinguish between _explicit_ null values `{id: 3, author: null}` and _implicit_ null values that correspond to the field being omitted `{id: 3}`. In this particular case, we forgot to accept explicit null values. Since the field is optional (meaning we accept implicit null values), it was nullable in the schema, like it was in pre-PDV times. But in practice we would reject explicit nulls.
This PR fixes this, and adds a test. Furthermore, it does a bit of a cleanup of the Mutation part of the schema, and more specifically of all insertion code.

This moves the previous (illegal) `Show` instance for `Hasura.Base.Error.Code` to a `ToJSON`
instance, and uses that in the error `ToJSON` instances.
Addressing https://github.com/hasura/graphql-engine-mono/pull/2277#issuecomment-911557169.
This PR is against #2277.
It adds a replacement derived `Show` instance, which is used:
- in the derived `Show` instance for `QErr`
- in some unit tests
Mostly verified that we didn't otherwise rely on the hand-rolled `Show`
instance by compiling without it (and a faked `QErr` instance), and seeing
that the only compile failures were in tests. (Compare the individual commits.)

When adding object relationships, we set the nullability of the generated GraphQL field based on whether the database backend enforces that the referenced data always exists. For manual relationships (corresponding to `manual_configuration`), the database backend is unaware of any relationship between data, and hence such fields are always set to be nullable.
For relationships generated from foreign key constraints (corresponding to `foreign_key_constraint_on`), we distinguish between two cases:
1. The "forward" object relationship from a referencing table (i.e. which has the foreign key constraint) to a referenced table. This should be set to be non-nullable when all referencing columns are non-nullable. But in fact, it used to set it to be non-nullable if *any* referencing column is non-nullable, which is only correct in Postgres when `MATCH FULL` is set (a flag we don't consider). This fixes that by changing a boolean conjunction to a disjunction.
2. The "reverse" object relationship from a referenced table to a referencing table which has the foreign key constraint. This should always be set to be nullable. But in fact, it used to always be set to non-nullable, as was reported in hasura/graphql-engine#7201. This fixes that.
Moreover, we have moved the computation of the nullability from `Hasura.RQL.DDL.Relationship` to `Hasura.GraphQL.Schema.Select`: this nullability used to be passed through the `riIsNullable` field of `RelInfo`, but for array relationships this information is not actually used, and moreover the remaining fields of `RelInfo` are already enough to deduce the nullability.
This also adds regression tests for both (1) and (2) above.

This removes the module re-exports of [Data.Align](https://hackage.haskell.org/package/semialign-1.2/docs/Data-Align.html) and [Data.These](https://hackage.haskell.org/package/these-1.1.1.1/docs/Data-These.html) from `Hasura.Prelude`. The reasoning being that they're not used widely and reasonably obscure, and that being explicit about the imports makes for an easier to understand codebase.
(I spent longer than I'd have liked earlier today figuring out where `align` in multitenant came from.
The right one not showing up on the first hoogle page doesn't help. Yes, better tool use could have
avoided that, but still...)
Do feel free to shoot this down, I won't insist on the change.
