This came about as I tried to add an instance over catalog versions and
found they were just simple integers most of the time (and in one case,
a float).
I think this change also clarifies how catalog versions work.

### Description
As part of the cache building process, we create / update / migrate the catalog that each DB uses as a place to store event trigger information. The function that decides how this should be done was doing an explicit `case ... of` on the backend tag, instead of delegating to one of the backend classes. The downsides of this is that:
- it adds a "friction point" where the backend matters in the core of the engine, which is otherwise written to be almost entirely backend-agnostic
- it creates imports from deep in the engine to the `Backends`, which we try to restrict to a very small set of clearly identified files (the `Instances` files)
- it is currently implemented using a "catch all" default case, which might not always be correct for new backends
This PR makes the catalog updating process a part of `BackendMetadata`, and cleans the corresponding schema cache code.

<!-- Thank you for ss in the Title above ^ -->
## Description
<!-- Please fill thier. -->
<!-- Describe the changes from a user's perspective -->
We don't have dependency reporting mechanism for `mssql_run_sql` API i.e when a database object (table, column etc.) is dropped through the API we should raise an exception if any dependencies (relationships, permissions etc.) with the database object exists in the metadata.
This PR addresses the above mentioned problem by
-> Integrating transaction to the API to rollback the SQL query execution if dependencies exists and exception is thrown
-> Accepting `cascade` optional field in the API payload to drop the dependencies, if any
-> Accepting `check_metadata_consistency` optional field to bypass (if value set to `false`) the dependency check

### Solution and Design
<!-- How is this iss -->
<!-- It's better if we elaborate -->
The design/solution follows the `run_sql` API implementation for Postgres backend.
### Steps to test and verify
<!-- If this is a fehis is a bug-fix, how do we verify the fix? -->
- Create author - article tables and track them
- Defined object and array relationships
- Try to drop the article table without cascade or cascade set to `false`
- The server should raise the relationship dependency exists exception

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

## Description
This PR fixes an oversight in the implementation of the resolvers of different backends. To implement resolution from environment variables, both MSSQL and BigQuery were directly fetching the process' environment variables, instead of using the careful curated set we thread from main. It was working just fine on OSS, but is failing on Cloud.
This PR fixes this by adding an additional argument to `resolveSourceConfig`, to ensure that backends always use the correct set of variables.

event catalog:
- `hdb_catalog` is no longer automatically created
- catalog is initialised when the first event trigger is created
- catalog initialisation is done during the schema cache build, using `ArrowCache` so it is only run in response to a change to the set of event triggers
event queue:
- `processEventQueue` thread is prevented from starting when `HASURA_GRAPHQL_EVENTS_FETCH_INTERVAL=0`
- `processEventQueue` thread only processes sources for which at least one event trigger exists in some table in the source
