StreetDealsCard фетчит /sales-vs-listings (не из estimate prop) → без засева
queryKey возвращал null (секция «По вашей улице» отсутствовала). Добавлен
FIXTURE_SALES (SalesVsListingsResponse, street+pairs) + seed
["trade-in","sales-vs-listings",address,area,rooms]. Теперь все 17 секций 1:1
с page.tsx (verified локально: 11 section-kicker'ов вкл. «По вашей улице»).

Refs #801.
