"""Per-city SERP location URL builders (#12 fix EKB-leak в oblast city-sweep).

Проблема: avito/cian/yandex провайдеры хардкодили ЕКБ-локацию (путь /ekaterinburg/,
CIAN_EKB_REGION_ID, _EKB_RGID) мимо anchor'а oblast-города → city-sweep целевого
города (напр. Н.Тагил) фактически скрейпил ЕКБ, n_analogs=0. Фикс — новые
kw-параметры (avito: target_city_slug уже был #2487, теперь и в ПУТИ URL;
cian: city_region_id; yandex: city_rgid), все дефолт None → ЕКБ-поведение
byte-identical прежнему (back-compat critical).

No network / no DB — чистые URL-билдеры на stub-конфиге.
