PHPStan workflow + PHPStan fixes

[DjordyKoert]

I noticed that PHPStan was available but not actually being used.

This PR contains a few changes & fixes, namely:

• PHPStan is now ran in CI
• Added PHPStan script (running PHPStan locally)
• A bunch of fixes that I encountered while running PHPStan locally
  • I was not able to fix some though because I don't have the required knowledge of these parts (or maybe some of these are actually bugged currently) . These should be added to baseline or fixed if someone knows how to.

Thanks for the work, I'm going to convert this into a draft until it's ready!

@Boy132 I see that you have opened #343 to fix the remaining issues. Should the current errors be added to a phpstan baseline or will this be merged with a failing PHPStan job?

We will properly merge #343 first and then your PR. Then all phpstan errors should be fixed.
