refactor: remove AI profile functionality and related components

- Deleted the AI profile management feature, including all associated views, hooks, and types.
- Updated settings and navigation components to remove references to AI profiles.
- Adjusted local storage and settings synchronization logic to reflect the removal of AI profiles.
- Cleaned up tests and utility functions that were dependent on the AI profile feature.

These changes streamline the application by eliminating unused functionality, improving maintainability and reducing complexity.
