feat: Implement screen group screens duplication in menu copy service

- Added a new method `copyScreenGroupScreens` to handle the duplication of screen group screens during the menu copy process.
- Implemented logic to create a mapping of screen group IDs from the source to the target company.
- Enhanced the existing menu copy functionality to include the copying of screen group screens, ensuring that the screen-role and display order are preserved.
- Added logging for better traceability of the duplication process.

This update improves the menu copy service by allowing for a more comprehensive duplication of associated screen group screens, enhancing the overall functionality of the menu management system.
