Add Batch Process Equipment Registration Functionality

- Implemented a new endpoint for batch registration of process equipment, allowing users to add multiple equipment codes at once while skipping duplicates.
- Enhanced error handling to provide detailed feedback on the registration process, including the number of successfully inserted and skipped items.
- Updated the process info routes to include the new batch registration functionality.
