home: hide dates on Featured posts site-wide; remove BB-AI trends sidebar

Dates
- FeaturedBentoFromDb hero + 4-up rail no longer render `ago(wp_published_at)`.
  The whole component renders only Featured-category posts (filter is
  category ILIKE 'featured'), so dropping the date display globally inside
  it satisfies the "Featured posts have no date" requirement.
- /gear and /technology category cards: wrap the existing `{article.date}`
  output in `{article.category !== "Featured" && ...}` so only non-Featured
  posts continue to show their publish date.
- All other category landing pages, /news/<slug> detail, ArticleFeed, and
  LiveWireTicker either don't render a visible article date or only use it
  for SEO/structured-data fields (kept).

Trends sidebar
- Remove `BB AI · detected trends` block from the homepage (between
  ArticleFeed and NewsletterSignup). Drop the unused import and delete
  the orphaned TrendsSidebar.tsx component file. The detect-trends data
  fetch and `bb_pulse_dot` mini-widget are gone from the page; nothing
  else referenced them.
