fix(analytics): recommend page UI — caveat badge wrap + headline baseline label

Two UX nits:
- Caveats badge had whiteSpace:nowrap on a 250-char data_caveat → overflowed
  visibly outside the section in the screenshot. Drop nowrap, keep small
  font + light grey background. Reads as a compact note.
- Headline KPIs (369 млн ₽ · 19.4 мес · темп 6.0 · ликв 97/100) are
  computed by backend at price_factor=1.0, while live KPI cards below
  recompute with the current slider position. When user moves price to
  +40% the discrepancy is confusing. Append small grey '(базовая цена)'
  marker after headline with a tooltip explaining baseline vs live.
