Финальный PR issue #2045 (BE-3): GET /api/v1/trade-in/location-coef для
LocationDrawer. FDW foreign table -> локальное зеркало osm_poi_ekb_local
(TRUNCATE+INSERT, тот же паттерн что cad_buildings_local/cadastral_geo_match,
избегает ~1.16s/row FDW round-trip) -> straight-line POI-скоринг, портированный
из Site Finder poi_score.py::compute_poi_weighted_top7 (CATEGORY_WEIGHTS as-is,
радиус 1200м для квартир вместо Ptica 2000м для участков). score->coef -
новая MVP-эвристика (0.95..1.05, не откалибрована на реальных дельтах).

Graceful fallback (не 500, не фабрикуем факторы): пустая/не отрефрешенная
osm_poi_ekb_local или отсутствие lat/lon у оценки -> coef=1.0, factors=[],
geo_source="unavailable".

Scheduler: source=osm_poi_ekb_refresh, daily, зарегистрирован и в боевом
dispatch (scheduler.py), и в kit-registry (product_handlers.py) - иначе
test_kit_registry_completeness падает на ship-dark инварианте (#2192).

Frontend wiring (mappers.ts/LocationDrawer.tsx) - вне scope, отдельная задача
после проверки endpoint'а curl'ом на деплое.
