feat: implement background task architecture for code quality scans

- Add status fields to ArchitectureScan model (status, started_at,
  completed_at, error_message, progress_message)
- Create database migration for new status fields
- Create background task function execute_code_quality_scan()
- Update API to return 202 with job IDs and support polling
- Add code quality scans to unified BackgroundTasksService
- Integrate scans into background tasks API and page
- Implement frontend polling with 3-second interval
- Add progress banner showing scan status
- Users can navigate away while scans run in background
- Document the implementation in architecture docs
