refactor: remove suggestions routes and related logic

This commit removes the suggestions routes and associated files from the server, streamlining the codebase. The `suggestionsModel` has been replaced with `ideationModel` across various components, including UI and service layers, to better reflect the updated functionality. Additionally, adjustments were made to ensure that the ideation service correctly utilizes the new model configuration.

- Deleted suggestions routes and their handlers.
- Updated references from `suggestionsModel` to `ideationModel` in settings and UI components.
- Refactored related logic in the ideation service to align with the new model structure.
