feat: enhance ideation routes with event handling and new suggestion feature

- Updated the ideation routes to include an EventEmitter for better event management.
- Added a new endpoint to handle adding suggestions to the board, ensuring consistent category mapping.
- Modified existing routes to emit events for idea creation, update, and deletion, improving frontend notifications.
- Refactored the convert and create idea handlers to utilize the new event system.
- Removed static guided prompts data in favor of dynamic fetching from the backend API.
