"""Тесты build_ird_analyze_block (#1067 D9b analyze-wiring, #1130 krt-from-db).

DB/сеть не дёргаются: мокаем parcel_ird_overlaps + get_or_fetch_zone_regulation + _krt_at
(module-level) и передаём fake EKBGeoportalClient. Проверяем сборку блока, split opportunity_*,
graceful-деградацию каждого источника, skip geoportal при отсутствии centroid.

#1130: krt теперь из DB (ekb_krt_geometry) — клиент WFS больше НЕ вызывается для слоя «krt».
_krt_at(db, lon, lat) мокается на уровне модуля.
