feat: Implement protocol discovery service with auto-discovery capabilities

- Add ProtocolDiscoveryService with network scanning for all protocols
- Create discovery API endpoints for scan management and results
- Implement discovery UI components in dashboard
- Add comprehensive unit tests for discovery functionality
- Integrate discovery with configuration manager for automatic mapping creation
- Support background task execution for long-running discovery scans
- Include discovery status monitoring and recent discoveries endpoints
