fix: use fuzzy title matching in _resolve_key_via_search

- Add _normalize_title() to strip anime suffixes (TV, OVA, Movie, etc.)
- Add _titles_match() using SequenceMatcher for similarity (threshold 0.85)
- Replace exact string match with fuzzy match to fix skipped folders
- Add debug logging for title mismatches and multiple results
- Set LOG_LEVEL=DEBUG in docker-compose.yml
