cross-link: companies-in-this-story sidebar + unified company search

Feature 1 — sidebar
  Adds a "Companies in this story" panel on every news article that
  surfaces every directory company my linker matched in the body. Each
  tile shows logo, name, Sponsor / NAB 26 / IBC badges, and a one-sentence
  bio. Tiles link to /manufacturers/<slug> and carry data-company-slug so
  the global hover card pops on hover too.

  Extends company-mentions.ts with linkifyAndExtractMentions() that
  returns both the linked HTML and the ordered list of matched slugs in
  one pass, so /news/[slug] doesn't re-scan the body for the sidebar.

Feature 2 — unified typeahead
  /api/search/suggest now returns { companies, items } — companies are
  matched against bb.tracked_companies (directory_visible=true), capped
  at 6, ordered by featured → mention_count, then bumped if they're an
  active advertiser on broadcastbeat (adv schema lookup).

  Header search dropdown renders a "Companies" section at the top with
  logo, name, Sponsor badge (active advertiser) or NAB 26 badge, above
  the existing "Stories" results. Each company link carries
  data-company-slug so the hover card works in the dropdown too.
