fix: delete stale matches when score drops below threshold or listing type changes

matchPropertyToSearches now:
- scores every search (listing type mismatch = 0 score)
- score >= 20: create or update match
- score < 20 AND existing match: delete stale record

Prevents outdated match records after criteria/weight updates.
