fix(estimator): radius (source,source_id) dedup + split-house corridor disclosure (audit #1871 P2)
Два P2-фикса в чувствительном estimator.py, оба за флагами.

DEDUP (estimate_radius_dedup_enabled, default ON):
radius-путь _fetch_analogs (Tier S-canonical/S-fallback/H/W) кэпил только
per-address (rn_addr ≤ MAX_ANALOGS_PER_ADDRESS=5), но (source,source_id)-дубли
делят один address и выживали на разных rn_addr рангах → раздували n_analogs
(prod 2026-06-23: yandex 48, cian 9, n1 5 excess). Добавлен rn_dup-window
PARTITION BY source, CASE(id:source_id|url:source_url|ctid) ORDER BY scraped_at
DESC + AND rn_dup=1 во все 4 тира — зеркалит anchor-dedup (:1556). CASE/ctid-guard
не схлопывает legacy NULL-source_id. ctid доступен (все тиры FROM listings
single-table). psycopg3: column::type (легально), bind-param :: отсутствует.

SPLIT DISCLOSURE (estimate_wide_corridor_disclosure_enabled, default OFF):
Tier A матчит по address-regex (намеренно — дом дробится на house_id), на
split-доме разной этажности comp_min..max растягивает коридор до 148-170%.
При corridor_pct > threshold (0.6) → понизить confidence на ступень + caveat
«дом разбит на секции разной этажности — оценка ориентировочная». НЕ трогает
point/median/range — только confidence+explanation. Helper _downgrade_confidence.
Default OFF (no-regress, включим осознанно). Merge house_id отклонён (recon:
вреден — Tier A намеренно обходит house_id-группировку).

Тесты: +22 (dedup 4 тира + семантика + psycopg3-regex guard; split disclosure
через реальный _run_estimate harness + does-not-touch-median/range + helper).
399 estimator passed, ruff clean, mypy pre-existing-only.
