maint: misc. refactorings, fixes, updates

- puts tests in the correct location of github workflow
- fixes `.env` values not loading via `load_dotenv` - required early loading
- corrects many static type linting errors
- combines all inputs into a single class with validation
- formats markdown & python files, as well as output
- slightly improved log messages, caught potential attribute error
- updates dependencies
