Frontend for the new data, on both movie + TV detail pages:
- Photos: a backdrops rail → fullscreen lightbox (‹ › nav, keyboard arrows, Esc,
counter).
- Videos: a rail of every trailer/teaser/clip/featurette (YouTube thumbs) → opens
in the existing player modal.
- Details: budget / box office / language / country + keyword tag chips.
- Cast & Crew gets a 'View all N' → full-cast modal (clickable to person; TV shows
per-actor episode counts).
All cached server-side (instant re-open) and lazy-loaded images. Isolated; shell
tests cover the new sections + modals.
