fix: improve gallery lightbox UI for better user experience

- Removed photo filename display from lightbox for cleaner viewing
- Fixed z-index layering to ensure controls always appear above images
- Changed control elements from z-10 to z-20 for proper visibility
- Set image container to z-0 to prevent overlap with controls
- Ensures all buttons remain accessible regardless of image size or zoom
