feat: Implement process work standard routes and controller

- Added a new controller for managing process work standards, including CRUD operations for work items and routing processes.
- Introduced routes for fetching items with routing, retrieving routings with processes, and managing work items.
- Integrated the new process work standard routes into the main application file for API accessibility.
- Created a migration script for exporting data related to the new process work standard feature.
- Updated frontend components to support the new process work standard functionality, enhancing the overall user experience.
