Implement dynamic group management features with exclusions and mode handling

Enhanced the group management system by introducing dynamic group capabilities, allowing for the exclusion of elements from dynamic groups. Updated the Group and GroupItem models to support a new GroupMode, enabling the distinction between static and dynamic groups. Implemented API endpoints for excluding elements and updated related services to handle group composition based on the selected mode. Improved the frontend to accommodate these changes, including new API functions and UI components for managing exclusions and group modes, thereby enhancing the overall user experience in group management.
