refactor: Extract ConsentFilter and StatsDisplay components from ModerationGroupsPage

- Created ConsentFilter component with proper styling
- Created StatsDisplay component for statistics display
- Added ModerationGroupsPage.css to remove inline styles
- Removed 83 lines of inline CSS from ModerationGroupsPage
- Components now reusable across admin pages
- Added container wrappers and titles to both components
- Improved code maintainability and separation of concerns
