Use a stricter configuration for basedpyright

A type checker that isn't strict is a bad type checker

This will likely break all PRs :P

• This is the rare case where if you wish to bring your PR up to date with main, you might want to do a proper git merge as opposed to git rebase, so that you can bring your code up-to-date with these changes in that merge commit, rather than having to edit each commit in a rebase to be compatible. (Unless you only have 1-2 commits)

Note: Unknown type reporting is currently disabled, there is a comment in pyproject.toml where these are disabled mentioning that we should consider enabling them. This will however not be done in this PR, instead, it will be covered by a future PR (#333), as I'm not entirely certain if enabling these is a good idea for us, they introduce a LOT of work, and while they can definitely be beneficial, I'm not sure it's worth the annoyance that they bring. I don't really wish to discuss the pros/cons of this in this PR, that discussion should take place in the PR that attempts to enable them.

Note 2: I've added some TODO comments into the code-base, which were not actually resolved here. That's because these TODOs are completely unrelated to this PR and are essentially just issues that I've noticed while working on this. These should be fixed in another PR(s) some time in the future.
