refactor: Update category value handling to make menuObjid optional

- Modified the addCategoryValue function to allow menuObjid to be optional, accommodating scenarios where it may not be provided, such as in global management screens.
- Adjusted related service and controller logic to handle the absence of menuObjid gracefully, ensuring that the application remains robust and user-friendly.
- Enhanced the frontend components to reflect these changes, improving the overall user experience when adding category values across multiple companies.
