refactor(ui): update frontend components for stream check

Update frontend components to use stream check API:
- Refactor ModelTestConfigPanel to use stream check config
- Update API layer to use stream_check commands
- Add HealthStatus type and StreamCheckResult interface
- Update ProviderList to use new health check integration
- Update AutoFailoverConfigPanel with stream check references
- Improve UI layout and configuration options

This completes the frontend migration from model_test to stream_check.
