Fix TV processor TIER 2 fallback logic for NFO files with aired but no dateadded

The issue was that TIER 2 (NFO cache) wasn't applying the aired date fallback
when NFO files contained aired dates but no dateadded values. This caused
episodes like "The Chosen" to show "no date added just air" because the
system would find lockdata in TIER 2 but reject it due to missing dateadded,
without applying the fallback logic.

Changes:
- Enhanced TIER 2 NFO processing to apply aired->dateadded fallback
- Added debug logging for NFO fallback cases
- Updated version to 2.0.23
