Add real-time upgrade progress tracking via status file

- upgrade.sh now writes status to /data/coolify/source/.upgrade-status
- New /api/upgrade-status endpoint reads status file for real progress
- Frontend polls status API instead of simulating progress
- Falls back to health check when service goes down during restart
