feat: Enhance dynamic form and BOM item editor functionality

- Added support for updating the `updated_date` field in the DynamicFormService, ensuring accurate timestamp management.
- Refactored the BomItemEditorComponent to improve data handling by filtering valid fields before saving, enhancing data integrity.
- Introduced a mechanism to track existing item IDs to prevent duplicates during item addition, improving user experience and data consistency.
- Streamlined the save process in ButtonActionExecutor by reorganizing the event handling logic, ensuring better integration with EditModal components.
