fix(dq): устранено переполнение памяти проверок

- Зачем:
  - параллельный DQ выгружал деловые ключи в Python и исчерпывал 640 МиБ планировщика.
- Что:
  - четыре сверки агрегируют дневные итоги и ограниченную диагностику в ClickHouse.
  - коробка планировщика поднята до 1,5 ГиБ, локальные пределы задач удалены.
  - измерения и граница между SQL и Python записаны в документации.
- Проверка:
  - make lint, make config-test, make smoke, make check-clickhouse, make check-services.
  - полный etl_pipeline, красный и восстановительный прогоны dq_check.
