Phase 6C featured carousel + Phase 2 event tag chips

FeaturedCarouselServer (RSC) pulls 5 most recent featured=true rows from
bb.ai_rewritten_articles UNION bb.wp_imported_posts, renders into the
client FeaturedCarousel component: 4s auto-advance (pause on hover),
chevron + dot nav + NN/NN counter, [ID xxxx] / [CATEGORY] badges,
serif headline, lede, optional neural-summary box with corner brackets +
confidence + entity chips, byline with initials avatar. Replaces the
FeaturedBento on the homepage.

Seeded bb.wp_imported_posts.featured = TRUE on 5 recent posts so the
carousel renders out-of-the-box (Amagi, Riedel, LiveU BroadcastAsia,
Cobalt Best-of-Show, Leader MPTS).

Phase 2 UI:
  EventTagPicker (client) — chip multi-select reading bb.events,
                            writing to bb.article_events via
                            /api/admin/review-queue/[id]/events.
                            article_table=ai_rewritten for now;
                            future submission-form integration will
                            cover other tables.
