Integrate real device detection into Dashboard UI

- Replace simulated dongle detection with actual kp.core.scan_devices()
- Display real device series (KL520, KL720, etc.) and port IDs in UI
- Add device information management methods (get_detected_devices, refresh_dongle_detection, etc.)
- Enhanced performance estimation based on actual detected devices
- Add device-specific optimization suggestions and warnings
- Fallback to simulation mode if device scanning fails
- Store detected device info for use throughout the application

The Dashboard now shows real Kneron device information when "Detect Dongles" is clicked,
displaying format: "KL520 Dongle - Port 28" with total device count.
