In hasura/graphql-engine#7172, an issue was found where under certain conditions a JSON field from Postgres would be parsed as a GraphQL input object, which is not possible in general, and also unnecessary. Luckily, this was already fixed by the time `v2.0.6` got around, presumably thanks to 4a83bb1834. This adds a regression test.

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.

Replaces one instance of `mtl`-style effects with `transformers`-style, as this results in a measurable reduction in memory usage. The change is kept completely within one module.

Problem: The `metadata diff` is conventional where it takes the project metadata and w.r.t to the signs `---`, `+++`, it shows the diff output but it is not similar to git diff as taking the remote repo as base and `+` denotes it has, `-` not. So make the metadata diff output follow as git diff output
Solution: To change the order of arguments in diff function and assign `---` to server,`+++` to project, so that it will be similar to prev diff output

This should be mostly a no-op change, with one exception:
When limits are not disabled, but neither node nor depth limit
is configured, we no longer count nodes/depth uselessly.

We also added a missing `--network=host` to the postgres container, which it turns out improves performance numbers a bit (hopefully increases stability a bit too).

This removes the file `bahnql_query.yaml`, which is no longer being used.
a509a86eaa (hasura/graphql-engine#1117) changed the way we test the remote schema feature from using external GraphQL services to running our own mini GraphQL server for testing purposes. This gives us a lot of in-codebase flexibility on the behavior of "remote" GraphQL servers.
During this work, the `bahnql_query.yaml` test was swapped out for the `simple2_query.yaml` test. The former essentially tests if a field from a remote schema can be fetched, whereas the latter tests whether an entry can be fetched from the (non-remote!) database.
It's not clear to me why `bahnql_query.yaml` was no longer used. In any case, the relevant setup code was removed, and this test can no longer be run. Presumably we test such basic functionality already in many other ways.

### Description

This PR supersedes https://github.com/hasura/graphql-engine-mono/pull/1484. Apply `limit` to the table selection before joining relationship rows to improve query performance.

### Solution and Design
>
Prior to this change, we apply `LIMIT` and `OFFSET` to the outer selection from sub-query which includes joins for relationships. Now, we move `LIMIT` and `OFFSET` (if present) to inner selection of base table. But, this isn't done always! If there are order by relationships' columns we apply at the outer selection. To know more, please refer to [source code note](https://github.com/hasura/graphql-engine-mono/pull/2078/files#diff-46d868ee45d3eaac667cebb34731f573c77d5c9c8097bb9ccf1115fc07f65bfdR652).

This is just a one-off fix, based on running ormolu across
the code base, which uses GHC's parser in haddock mode.
### Description
Fixes several instances of illegal haddock comments.
### Related Issues
#1679
### Steps to test and verify
Run ormolu over the codebase. Prior to this change, it complains that it
can't parse certain files due to malformed Haddock comments, after it
doesn't (there are still some other errors).
### Limitations, known bugs & workarounds
This doesn't ensure that we don't introduce similar issues in the future;
that'll be dealt with once we implement #1679.
#### Breaking changes
- [x] No Breaking changes, only touches code comments
