Remove monolithic nfoguard.py and add comprehensive debug logging

- Remove 2467-line monolithic nfoguard.py file to prevent confusion
- Add debug prints to identify why NFO metadata isn't being added
- Track config.manage_nfo values and function calls
- Debug dateadded parameter passing through all tiers
- This will help identify if manage_nfo is disabled or function not called
