feat: Preserve TV episode NFO filenames matching video files
Local Docker Build (Dev) / build-dev (push) Successful in 29s
Details

Browse Source 
Instead of migrating long NFO names to standardized S01E01.nfo format,
now preserves original filenames that match video files while still
populating NFOGuard metadata (dateadded, aired, season, episode).

Changes:
- Added update_episode_nfo_preserving_name() method to NFOManager
- Added find_episode_nfo_matching_video() to locate NFO files by video name pattern
- Modified TVProcessor to update existing NFOs in-place rather than migrate names
- Episodes with existing NFOs now get "nfo_update_required" source for special handling

This maintains the user's preferred naming convention where NFO files
match their corresponding video files exactly.
