Summary by CodeRabbit

Bug Fixes
- Improved transaction reliability by ensuring automatic rollback on unexpected panics or failures.
- Added database-level timeout protections to guard against long-running statements and locks.
- Maintained existing foreign-key handling and commit behavior while strengthening error handling and rollback paths.
- Ensured timeout settings are applied transactionally and will roll back if they cannot be set.
