Refactoring (#327)

* chore: enable more linters and fix linter issues

* ci: enable linter checks on all branches and disable recurring checks

recurring linter checks don't make that much sense. The code & linter checks should not change on their own over night ;)

* chore: update packages

* Revert "chore: update packages"

This reverts commit 30250bf28c4b39e9e5b3af012a4e28ab036bf9af.

* chore: manually upgrade some packages
