feat: Enhance screen group deletion functionality with optional numbering rules deletion

- Added a new query parameter `deleteNumberingRules` to the `deleteScreenGroup` function, allowing users to specify if numbering rules should be deleted when a root screen group is removed.
- Updated the `deleteScreenGroup` controller to handle the deletion of numbering rules conditionally based on the new parameter.
- Enhanced the frontend `ScreenGroupTreeView` component to include a checkbox for users to confirm the deletion of numbering rules when deleting a root group, improving user control and clarity during deletion operations.
- Implemented appropriate warnings and messages to inform users about the implications of deleting numbering rules, ensuring better user experience and data integrity awareness.
