Make user_sessions migration idempotent for 1.2.7 compatibility

- Modified 20251005000000_add_user_sessions to check if table exists first
- Added existence checks for all indexes and foreign keys
- Migration now works for both fresh installs and 1.2.7 upgrades
- Prevents P3018 error by gracefully handling existing table
- Added comprehensive logging for debugging
