fix: enhance model provider popup functionality and loading state handling

- Updated the model provider popup to include loading state for marketplace plugins.
- Improved filtering logic for installed models and marketplace providers.
- Added tests to ensure correct behavior when no models are found and when query parameters are omitted.
- Refactored the handling of model lists to better manage installed and available models.
