feat: enhance suggestion generation with model and thinking level overrides

- Updated the generateSuggestions function to accept model and thinking level overrides, allowing for more flexible suggestion generation.
- Modified the API client and UI components to support passing these new parameters, improving user control over the suggestion process.
- Introduced a new phase model for AI Suggestions in settings, enhancing the overall functionality and user experience.
