Subject: [PATCH] feat(tradein/v2): wire overlays History/Analytics/Sources to
 real API (#2039 #2040 #2041)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

FE-2/3/4 on the FE-1 mappers architecture. Adds mapHistory/mapAnalytics/mapSources
(+helpers) to mappers.ts; HistoryView/AnalyticsView/SourcesView accept composite
data props (fixture default); SectionOverlay forwards overlay data; page.tsx adds
useEstimatePlacementHistory/useSalesVsListings/useEstimateSellTimeSensitivity and
feeds mapped data. FE-1 main dashboard untouched.

- History: house sales (placement-history); ДКП KPI/header (street-deals +
  sales-vs-listings); per-deal rows with REAL addr/date/listing-source/discount.
- Analytics: KPIs (экспозиция/торг/доля снятых), 4 sell-time tiers, price-history
  polylines computed from year×source, detail scatter.
- Sources: ad rows from analogs (real source/distance/url via safeUrl), deal rows
  from actual_deals (real source/tier/date), market KPIs.
- Un-hardcoded fabricated cells: DKP addr/date/source, deal date, deals footer count.
- FE-approx (TODO BE-1 #2043): CV, per-source counts, days_on_market->listing_date.

Verified: next build green (/v2 37.8 kB); tsx harness ran the 3 overlay mappers vs
real estimate 701795d8 (houseSales/KPIs/sellTime/priceHistory/scatter/ad+deal rows
correct). code-reviewer APPROVE after honesty fixes.
