feat(modal): add license restriction indicators to model modal

Add visual indicators for commercial license restrictions in the model modal. New CSS classes and JavaScript utilities handle the display of restriction icons for selling, renting, and image usage limitations. The modal header actions container has been restructured to accommodate the new license restriction section.

- Add `.modal-header-actions` and `.license-restrictions` CSS classes
- Implement commercial license icon configuration and rendering logic
- Normalize and sanitize commercial restriction values
- Update header layout to remove bottom margin for better visual alignment
