Add fill state (default false) to the Alpine lightbox data:
- FILL button (top-right, left of ✕): switches media to object-cover,
filling the entire overlay edge-to-edge; button turns heat pink
- FIT restores object-contain with padding; button returns to fog
- Keyboard shortcut F toggles fill while lightbox is open
- close() resets fill to false for the next open
- transition-all duration-300 on container padding and media for
a smooth morph between modes
