Replace Carousel with ScrollArea, remove embla-carousel dependency

- Delete carousel.tsx and replace all Carousel/CarouselContent/CarouselItem
  usage across title rows, cast carousel, continue watching, and explore
  sections with ScrollArea + scrollFade horizontal scroll
- Update ScrollArea to accept a `scrollFade` prop that renders a
  gradient edge overlay instead of the old per-site absolute div hack
- Remove "use client" directive from title-row and cast-carousel now
  that they have no client-side hooks
- Delete unused resizable.tsx; inline TypeBadge icon into TitleHero
  and delete the standalone type-badge.tsx file
- Add TitleTheme component for per-title accent color CSS injection
- Swap IconSparkles → IconThumbUp in recommendations section and grid
- Simplify ambient glow to a single size (remove mobile breakpoint override)
