The "Analyze" feature for SQL Server only partially worked. It would show the SQL generated, but not the execution plan. This is because SQL Server doesn't support generating a plan for prepared statements with parameters.
To work around this, we restructure the query as one without parameters. Instead, we replace each parameter with a variable. We declare the variables but don't set values. We then plan _that_, which works.
We run all this in a single query because local variables only last for a single transaction/batch.
This feature does not work for stored procedures.

This turns on the `partial-fields` warning, which yells at you if you try and create fields on sum types that end up being partial functions. These are dangerous; we had a bug because we introduced a new case to a data type, making the field accessors partial, and leading to a crash in certain cases.
This means that we have introduced a few wrappers in various places where the field names are useful, but we want to avoid partial matches.
Unfortunately this can be turned off by prefixing the field name with an underscore. Ideally we would try and avoid exporting any field names with underscores, but lenses make this hard. I have removed some underscores for the areas in which we've seen this break in the past.
We will have to be vigilant.

<!-- 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
