fix: improve main.py and utils.py, remove paths filter from scorecard workflow

- Remove 'paths' filter from scorecard.yml push trigger to run on all master pushes
- Refactor main.py to locally fetch WAKATIME_API_KEY env var and replace retry exhaustion logs with ValueError exceptions
- Reduce get_wakatime_stats retry attempts from 10 to 5 and raise on failure instead of returning None
- Update utils.py initialize_github to dynamically detect github.Auth.Token for compatibility with PyGithub changes
- Add missing test coverage for network error handling and update_readme content retrieval failure in main.py
- Refactor tests to reduce too-many-argument warnings and fix patch targets
