Fix dogfood pass-2: grid thumbs, AI view, featured/recent dedupe

- Portfolio cards: eager first-page load, cache-safe onLoad via ref,
  soft opacity while loading, error placeholder (no stuck black voids)
- Hide home view chips when primary category has zero projects (AI)
- Seed AI view with showOthers false; home Recent excludes Featured
- Slightly larger scroll-padding under sticky header
