trends sidebar cleanup: minimal display + beige/navy palette

Per Ryan 2026-05-15:
- Removed Vector pass footer (no audience value)
- Removed PHASE 6b comment
- Removed corner brackets + monitoring subtitle + rank prefix
- Top 5 entities now show as Sony +12 / Riedel +8 — entity name
  serif + count mono, right-aligned
- Background #F5EFEB (beige; #F5EFFEB had 7 hex chars, interpreted as
  #F5EFEB) via new --color-trends-bg token
- Text #2F4F5B (navy) via new --color-trends-text token
- Tokens added to redesign-tokens.css palette section
