feat(photos): adaptive aspect ratio per entry (portrait 4:5, landscape 4:3)

Portrait entries (first image taller than wide) get a 4:5 container —
Instagram's proven cap that prevents single photos dominating the screen.
Landscape entries keep 4:3. Aspect-ratio moved from slide to wrap so the
strip inherits it via height:100%.
