fix(db): prevent silent failures in sql_select

- Modify sql_select to return False on database exceptions instead of an empty result
- Update V3 Search endpoint to catch False results and return a 500 Internal Server Error
- Enhances error visibility for frontend developers and prevents misleading 200 OK responses during SQL errors
