Fix discovery service persistence and API issues

- Add persistent discovery service auto-initialization in start_dashboard.py
- Fix 'is_scanning' field in discovery status API
- Fix scan results API to handle dictionary data correctly
- Fix database schema issues for discovery_results table
- Add debugging for service initialization

Resolves issues with discovery service not persisting across restarts
and API endpoints returning incorrect data formats.
