fix: Script bug fixes (bare except, timezone, regex, test)

- collector.py, compliance_checker.py, trends.py: bare except -> specific
- db_helper.py: datetime.now() -> timezone.utc (8 occurrences)
- compliance_checker.py: regex \x08 -> \b word boundary + import json
- search_providers.py: minor fixes
- test_new_features.py: service reachability check retry
