feat: Update equipment handling in process management

- Enhanced the `getProcessEquipments` function to support matching both legacy equipment codes and new IDs, improving data retrieval accuracy.
- Updated the `availableEquipments` logic in the `ProcessMasterTab` component to handle both equipment codes and IDs, ensuring a seamless user experience when adding equipment.
- Improved error handling for equipment selection, providing user feedback when a selected equipment cannot be found.
- Refactored the display of equipment names to ensure accurate representation, even when equipment codes are not available.
