refactor tui to use model metadata for descriptions

- getTranscriptionModelOptions now uses provider.ModelsOfType() instead of hardcoded switch
- getLLMModelOptions now uses provider.ModelsOfType() instead of hardcoded switch
- added currentLang param to show language compatibility warnings on models
- buildModelLabel adds [size] for local models, [streaming] for streaming
- mapConfigProviderToRegistry maps config names to registry names
