Frontend changes for quality limiting feature:
- Add limitQualityToDevice state and handler
- Add AudioSettings interface fields for limit_quality_to_device and device_max_sample_rate
- Update handleBackendDeviceChange to send max_sample_rate when device changes
- Update handleOutputDeviceChange to find max_sample_rate from backend devices
- Add Settings UI toggle for "Limit Quality to Device"
This completes the quality limiting feature that prevents requesting tracks
that exceed the device's sample rate capabilities, ensuring bit-perfect playback.
