feat(gallery): add quick Like/Favorite actions on thumbnails across layouts

- Grid, Masonry, Mosaic, Timeline, Hero, and Carousel layouts now expose inline Like/Favorite buttons when feedback is enabled
- Respect requireNameEmail; prompt via identity modal before submitting feedback
- Wire feedback settings from GalleryView -> layouts via feedbackOptions

feat(lightbox): keep feedback usable while navigating

- Add initialShowFeedback prop; preserve panel state across navigation
- Offset Next button when feedback panel is open so it remains accessible
- Hide/avoid overlapping nav on small screens
