fix: comprehensive boolean compatibility for PostgreSQL and SQLite

- Add formatBoolean() usage to all boolean database queries
- Fix 36 boolean comparisons across 18 backend files
- Ensure compatibility between SQLite (0/1) and PostgreSQL (true/false)
- Update all WHERE clauses and UPDATE operations with boolean values

This completes the database compatibility fixes for production deployment.
All boolean operations now work correctly with both database systems.
