homepage: bento 3-up + 300x600 inline; word-safe excerpt; bigger sponsor logos

- FeaturedBentoFromDb: row below the hero is now a 3-up rail on the left
  with the Blackmagic 300x600 on the right, aligned with the hero's right
  edge. SidebarAdStack skips that 300x600 so the article-feed sidebar
  starts with the 300x250 stack instead.
- cleanExcerpt: render-time word-snap for excerpts that were hard-cut at a
  byte count (Matrox 50-years showed "Since 1976, the co" mid-word). Used
  on the bento hero subhead and the article-feed cards.
- SponsorLogoStrip: now also pulls every tracked_companies.featured=true
  brand (Rode, TBC Consoles, Plura, Autocue, Autoscript, Filmcraft,
  Lectrosonics, Prompter People, SanDisk, Sennheiser), and logos go from
  h-10/h-12 max-w-140 → h-14/h-16 max-w-180 with thicker padding.
