feat: gracefully handle removed models in UI

[daniel-lxs]

Summary

This PR implements graceful handling for models that have been removed from the catalog but are still selected in user configurations.

Changes

• UI Enhancement: Shows removed models in the dropdown with an '(unavailable)' label, allowing users to see their current selection even if it's no longer in the catalog
• Provider Switching: Automatically clears removed models when switching to a different provider, preventing invalid configurations from being carried over
• Internationalization: Added support for the 'unavailable' label across all 18 supported languages
• Test Coverage: Added comprehensive tests for removed model scenarios

Behavior

1. When a model is removed from the catalog but still selected:

   • The model remains visible in the dropdown with '(unavailable)' suffix
   • Users can continue using it until they switch providers or select a different model
   • The API handles any errors (400/404) which are displayed to the user

2. When switching providers:

   • If the current model was removed, it's automatically cleared
   • The new provider's default model is selected

Testing

All tests pass successfully:

• 15 tests passing in ApiOptions.spec.tsx
• Verified behavior with temporarily removed models
• Confirmed internationalization works correctly

Related Issues

Similar to #7392 but focused on graceful degradation rather than hiding providers.

Reviewed the latest commit that removes the deprecated roo/sonic model from the model catalog. This change is clean and consistent with the PR's goal of gracefully handling removed models. No issues found.

Changing type from Record<RooModelId, ModelInfo> to Record<string, ModelInfo> weakens type safety. If this is intended for flexibility, please add a clarifying comment.

Do we still need this one? Or is it duplicative of the work around deprecated models?
