fix(tradein/v2): address parse (Cyrillic \b bug) + scatter from listing_date (#2038)

QA on real prod estimate 701795d8 surfaced two mapper defects:
- STREET_RE used JS \b which does NOT word-boundary Cyrillic → street token never
  matched → object.address fell back to the bare house number ('14/3') and city
  mis-parsed ('14/3, Россия'). Rewrote parseAddress to handle both OSM (house-first)
  and DaData (city-first) orders; street keyword delimited by space, not \b. Now
  'улица Яскина, 14/3' + city 'Екатеринбург'.
- days_on_market is null across prod lots → scatter-mini rendered empty. Active
  analogs now fall back to 'days listed so far' = today-listing_date (deals still
  require a real days_on_market — today-deal-date is not exposure). TODO BE-1.

Verified via tsx harness against the real estimate (25/25); next build green.
