Merge api_dashboard_delete_endpoint branch, resolving conflicts

Integrated delete dashboard endpoint with existing update endpoint:
- Fixed merge conflicts in dashboard project plan
- Combined routes in mod.rs to support GET, PUT, and DELETE endpoints
- Organized test module imports alphabetically
