Review round 2 on #2626 (local houses fallback) found two HIGH-severity bugs
verified live against prod data:

1. _extract_local_house_token took the LAST digit-like token in the raw
   address, so "...Педагогическая, д 15, кв 11" resolved house=11 (apartment
   number) instead of 15 -- confidently returning a stranger's building with
   confidence='exact', written to geocode_cache. Fixed by stripping the
   apartment/office/floor/entrance tail (кв/оф/пом/подъезд/этаж -- NOT
   корп/к, which is part of the house number) before extracting the token.
   Fixes the exact prod case from the review plus the corpus+apartment
   combo ("д 26 к 1, кв 41" -> 26к1, not 41).

2. houses is not an EKB-only table (21% of rows with coords are outside the
   metro, some as far as another city) -- "улица Маяковского, 7" in houses
   resolves to Серов, not Екатеринбург, and use_local_ekb only gates the
   user's query text, not the source row. Added an is_within_ekb_bbox_wide
   check on every candidate row before it can become a match.

Also addressed two MEDIUM findings from the same review:

3. The "<номер> -> <номер>к1" corpus guess only checked uniqueness among
   к1-labelled rows, so real multi-building addresses (Онуфриева 24: к1/к2/к3,
   250-400m apart) resolved confidently to к1 anyway. Guess is now skipped
   when any other corpus/slash variant of the same base number exists among
   the street's candidates.

4. Houses-fallback results are no longer cached in geocode_cache -- the
   source (scraped listings) is less reliable than geoportal/cadastral/
   Nominatim, and the lookup is cheap/local, so caching only extended the
   lifetime of a possible bad match. Side benefit: address_refined now
   survives every repeat request of the same raw address, not just the
   first.

Also added ORDER BY address, id to the underlying query so the coordinate
dedup picks a deterministic row (LOW finding #5).

14 new/updated tests in test_geocoder_local_houses_fallback.py cover all
five findings against real prod address/houses-row fixtures. Full geocoder
+ dadata + estimator/pdf regression suite (402 tests) green.

c75206c348 fix(tradein/geocoder): local houses fallback + downgrade DaData CLEAN-disabled noise
28/1084 прод-оценок имели lat IS NULL — гарантированный ноль аналогов, клиент
не получал оценку вовсе. Дом уже был в houses (скрейпленные листинги), но не
резолвился ни geoportal/cad_buildings, ни Nominatim: разговорное/усечённое имя
улицы («Онуфриева» вместо ГАР-каноничного «Начдива Онуфриева») или отсутствующий
в вводе корпус («49» вместо реального «49к1»). Добавлен последний тир geocode()
с двумя defensive-допущениями (суффиксный матч улицы + опциональная догадка
«номер+к1») — при любой неоднозначности возвращает None, а не гадает; проверено
живыми прод-адресами (Онуфриева/Хрустальногорская резолвятся, Крестинского
корректно остаётся неоднозначным — два разных дома в houses под одним номером).

Отдельно: HTTP 403 «услуга CLEAN выключена на аккаунте» логировался как ERROR
на каждый /estimate (164 события) — это статичная конфигурация аккаунта, а не
сбой; понижено до WARNING (первый раз за процесс) + DEBUG на повторы, чтобы
ERROR продолжал значить настоящую проблему.
