Chore: Make linter happy (#1256)

* refactor: remove unused imports

* fix: replace NotImplemented with NotImplementedError

* refactor: resolve E722 (do not use bare 'except')

* refactor: remove unused variable

* refactor: remove unused imports

* refactor: ignore unused imports that will be used in the future

* refactor: resolve W293 (blank line contains whitespace)

* refactor: resolve F541 (f-string is missing placeholders)
