### Description
This PR is the result of a discussion in #3363. Namely, we would like to remove all uses of `unsafeMkName`, or at the very least document every single one of them, to avoid similar issues. To do so, this PR does the following:
- it adds a hlint suggestion not to use that function:
- suggestions don't mark the PR as failed, but will be shown at review time
- it is possible to disable that hint with `{- HLINT ignore myFunction "unsafe" -}`
- wherever possible, it removes uses of `unsafeMkName` in favour of `mkName`
- it adds a comment with a tracking issue for the two remaining uses:
- #3478
- #3479
### Remaining work
- discuss whether this hint should make the linter step fail, since the linter step isn't required to merge anyway, and there is a way to disable the hint wherever we think the use of that function is acceptable
- check that none of those uses were load-bearing and result in errors now

So far we've only used `hlint` to lint the OSS code. This moves some things around to lint the Pro code as well.
Note that the CI action only runs `hlint` on Haskell files that are _changed_ by a PR, relative to its merge-base (usually `main`).
As a reminder, you can use the `ignore-server-hlint-checks` label to prevent this from blocking a merge.
