### Description
(This PR is better reviewed commit by commit.)
This PR is an aggregation of small incremental changes to Pro's init:
- it deletes some dead code,
- it starts reorganizing the code of that file by sections, similar to OSS' init,
- it extracts and cleans up license key cache init (groups several blocks of code in one separate function)
- makes some changes to a service class to reduce the dependency on `_acAppStateRef`
This PR is a first step: our goal is to move the schema cache build _in_ the app monad, in order to achieve #8344. To do so, we will need to remove `_acAppStateRef` from Pro's `AppContext`. There are two different paths we can take from here, which is why i cut this PR here:
- the first would be to change the different instances we implement on `AppM` to take as an argument the parts of the schema cache they depend on, rather than reading them from `_acAppStateRef`; as of this PR, `MetricsConfig` is the only such field;
- the second would be to apply the same strategy we already used for the TLSAllowList, and use a `IORef` that can be updated after the schema cache is built; this change would have a smaller footprint, but introduces one new `IORef` per such field, which feels something we don't want to generalize

### Description
If i understand correctly, the _value_ of a feature flag **can** change at runtime. Since this has an impact on how the schema cache is built, this PR makes the value of the flag a part of the cache's "dynamic" config, therefore making it an arrow-ish argument for the incremental framework. It also removes `CheckFeatureFlag` from the static config, now obsolete.

### Description
This PR removes `ServerConfigCtx` and `HasServerConfigCtx`. Instead, it favours different approaches:
- when the code was only using one field, it passes that field explicitly (usually `SQLGenCtx` or `CheckFeatureFlag`)
- when the code was using several fields, but in only one function, it inlines
- for the cache build, it introduces `CacheStaticConfig` and `CacheDynamicConfig`, which are subsets of `AppEnv` and `AppContext` respectively
The main goal of this is to help with the modularization of the engine: as `ServerConfigCtx` had fields whose types were imported from several unrelated parts of the engine, using it tied together parts of the engine that should not be aware of one another (such as tying together `Hasura.LogicalModel` and `Hasura.GraphQL.Schema`).
The bulk of this PR is a change to the cache build, as a follow up to #8509: instead of giving the entire `ServerConfigCtx` as a incremental rule argument, we only give the new `CacheDynamicConfig` struct, which has fewer fields. The other required fields, that were coming from the `AppEnv`, are now given via the `HasCacheStaticConfig` constraint, which is a "subset" of `HasAppEnv`.
(Some further work could include moving `StringifyNumbers` out of `GraphQL.Schema.Options`, given how it is used all across the codebase, including in `RQL.DML`.)

- Remove `MonadMetadataStorageQueryAPI` which was only implemented by a default implementation
- Introduce `TransT` which can be used to easily derive `lift`ing implementations for `MonadBlaBlaBla` classes

## Description
This PR is a incremental step towards achieving the goal of #8344. It is a less ambitious version of #8484.
This PR removes all references to `HasServerConfigCtx` from the cache build and removes `ServerConfigCtx` from `CacheBuildParams`, making `ServerConfigCtx` an argument being passed around manually instead. This has several benefits: by making it an arrow argument, we now properly integrate the fields that change over time in the dependency framework, as they should be, and we can clean up some of the top-level app code.
## Implementation
In practice, this PR introduces a `HasServerConfigCtx` instance for `CacheRWT`, the monad we use to build the cache, so we can retrieve the `ServerConfigCtx` in the implementation of `CacheRWM`. This contributes to reducing the amount of `HasServerConfigCtx` in the code: we can remove `SchemaUpdateT` altogether, and we can remove the `HasServerConfigCtx` instance of `Handler`. This makes `HasServerConfigCtx` almost **an implementation detail of the Metadata API**.
This first step is enough to achieve the goal of #8344: we can now build the schema cache in the app monad, since we no longer rely on `HasServerConfigCtx` to build it.
## Drawbacks
This PR does not attempt to remove the use of `ServerConfigCtx` itself in the schema cache build: doing so would make this PR much much bigger. Ideally, to avoid having all the static fields given as arrow-ish arguments to the cache, we could depend on `HasAppEnv` in the cache build, and use `AppContext` as an arrow argument. But making the cache build depend on the full `AppEnv` and `AppContext` creates a lot of circular imports; and since removing `ServerConfigCtx` itself isn't required to achieve #8344, this PR keeps it wholesale and defers cleaning it to a future PR.
A negative consequence of this is that we need an `Eq` instance on `ServerConfigCtx`, and that instance is inelegant.
## Future work
There are several further steps we can take in parallel after this is merged. First, again, we can make a new version of #8344, removing `CacheBuild`, FINALLY. As for `ServerConfigCtx`, we can split it / rename it to make ad-hoc structures. If it turns out that `ServerConfigCtx` is only ever used for the schema cache build, we could split it between `CacheBuildEnv` and `CacheBuildContext`, which will be subsets of `AppEnv` and `AppContext`, avoiding import loops.

### Description
This PR is one more step towards #8344: it splits `initializeContext` into two parts: the first one builds the `AppEnv`, and the second builds the `AppContext` and its corresponding `AppStateRef`. Splitting it allows us to run the first schema cache build _in the app monad_, which was one of the steps required to remove `CacheBuild`, and ultimately to achieve #8344, which in turn is a blocker for several projects.

### Description
This small PR is on top of #8440. It continues the cleanup of `Hasura/App` by grouping together all instances on the app monad, renaming the app monad, and removing its `m` parameter.

### Description
As part of another project (the continuation of #8421), i have started a cleanup of `Hasura.App`, focusing on deleting old code and grouping together things that belong together. This quickly grew into a refactor of `GlobalCtx`, now renamed into `BasicConnectionInfo`. This small refactor adds comments, and aims at making clear what the purpose of those types and functions is.
Furthermore, it also changes the way the default postgres connection info is created, by making that part of the process of creating the `BasicConnectionInfo`, to deduplicate similar effort across different files.
This is expected to be a no-op.
