perf(site-finder): air-quality TTL-кэш + neighbors_summary 2→1 SQL (#1130 Phase B)
Phase B продолжает hot-path latency cut'ы analyze_parcel поверх Phase A (PR #1194):

1. get_air_quality_cached в weather_cache (третий TTL-слот рядом с forecast/climate):
   - hit-TTL 1h (hourly bucket Open-Meteo), negative-TTL 5min.
   - timeout 5s → 2s.
   - single-flight под per-cache threading.Lock.
   - Снимает 0.26с на cache-hit и до 5с при DNS-fail (тот же антипаттерн,
     что был у forecast/climate до Phase A).

2. _neighbors_summary: 2 SQL → 1 statement.
   - WITH neighbors AS (... LIMIT 30), overlaps AS (... LIMIT 5)
   - + COALESCE(json_agg(row_to_json(...)), '[]'::json) в основном SELECT.
   - Один round-trip вместо двух (~-47 ms на каждый analyze).
   - Семантика идентична: те же ST_DWithin(geom, point, 100m) для neighbors,
     ST_Intersects + ST_Area для overlaps. Anti-fakes guards (_COST_PER_M2_MIN/MAX,
     float() try/except, >50 m² overlap) сохранены.

Формат возвращаемых dict не меняется (frontend контракт). 5 новых юнит-тестов в
test_weather_cache.py (TestAirQualityCache: hot-hit, negative, empty-hourly,
separate-from-weather, ttl-expires). 7 файлов API-тестов обновили patch-цель
_fetch_air_quality_sync → get_air_quality_cached.
