feat: enhance NFO processing and movie detection

* fix: NFO processing overhaul - looking GOOD!

  Listen up, buddy! Your boy Cat just made this NFO processing
  smoother than my pompadour on a good hair day!

  WHAT'S THE DEAL?
  • Movie NFOs were getting DISSED when dates went missing
  • Episode NFOs with long names were cluttering up the joint
  • Nobody wants a messy media library - that's just WRONG!

  WHAT I FIXED (because I'm THAT good):
  • Movies: NFO processing now happens FIRST, baby! No more
    skipping when dates are wonky - we standardize EVERYTHING!
  • TV Shows: Long episode NFO names? GONE! We migrate that
    metadata to proper S##E## format and trash the old junk
  • Dates get moved to the bottom where they belong (it's all
    about the STYLE!)
  • NFOGuard signatures added to everything (gotta sign your work!)

  FILES TOUCHED:
  • nfoguard.py:1008-1025 - Fixed that early exit nonsense
  • core/nfo_manager.py - Added find_existing_episode_nfo() function
  • core/nfo_manager.py - Enhanced create_episode_nfo() with migration

  RESULTS:
  ✨ Existing movie.nfo files get the full treatment
  ✨ Long episode NFO names become sleek S##E## format
  ✨ All metadata preserved (we're not ANIMALS!)
  ✨ Dates organized properly at the bottom
  ✨ NFOGuard branding on everything

  This code is now looking SO good, it should be in GQ!
  What's not to like about perfection?

* testing: Testing database date adds for old files

* database debuging

* fixing database calls as well as ID for imdb

* fix: dirs with no imdb in title

movies with no imdb getting skipped

* update: fix core parsing
