fix: Use comprehensive IMDb detection for movie batch validation

- Replace simple string search with find_movie_imdb_id() method
- Check directory name, filenames, and NFO file content for IMDb ID
- Handle both full IMDb IDs (tt26394837) and number formats
- Add detailed logging for detected vs expected IMDb matching
- Fix validation failures when IMDb ID is in filename/NFO but not directory name

Resolves movie webhook processing failures when directory lacks IMDb ID
but files contain proper identification.
