Refactor API routes and controllers for improved structure and clarity

- Updated API route structure to remove versioning and consolidate endpoints.
- Refactored routing in `server.go` to use a unified `/api` prefix for all controllers.
- Added new `ChannelController`, `ConversationController`, and `MessageController` to handle specific API functionalities.
- Removed deprecated `OpenImContextMiddleware` and related logic.
- Enhanced channel validation logic in `ChannelService` and `ChannelRepository`.
- Updated frontend API calls to align with new endpoint structure.
