`cad_parcels_geom` — VIEW над `cad_parcels` где `geom` nullable (~964 prod-
строк с NULL geom задокументировано в analyze:1504-1507). Без фильтра
`geom IS NOT NULL` в UNION-ветках:
- NULL-строка из ранней ветки (`cad_quarters_geom`) ПЕРЕКРЫВАЕТ валидную
  геометрию из поздней (`cad_parcels_geom`) — LIMIT 1 берёт первую попавшуюся.
- ST_Centroid(NULL) → NULL → coord_row.lat = NULL → float(None) → TypeError
  → 500 (вместо честного 404).

Guard `if not coord_row` НЕ ловил эту дыру: RowMapping с None-полями
truthy. Зеркало паттерна из analyze (parcels.py:1418-1438) для обоих
эндпоинтов (`/isochrones` + `/poi-score`):
1. `AND geom IS NOT NULL` во ВСЕХ ветках UNION.
2. Belt-and-suspenders: явная проверка `coord_row.get("lat") is None`
   на случай топологически битого polygon'а (NOT-NULL geom, NULL centroid).

26 analyze/isochrones/poi-score юнит-тестов зелёные. ruff clean.

Closes #1201
