/**
 * Step-handlers для moysklad-import.
 *
 * Поднимаем mock MoySklad (lib/moysklad-mock.ts) на фиксированном порту, на
 * который заранее наведён API через MoySklad:BaseUrl. Прогоняем импорт через
 * реальные эндпоинты /api/admin/moysklad/* + фоновый job /api/admin/jobs/{id}
 * и проверяем результат и в job-счётчиках, и в БД (маппинг полей).
 *
 * Порт mock-сервера ДОЛЖЕН совпадать с MoySklad__BaseUrl, с которым запущен API
 * (см. tests/e2e/README / запуск): http://127.0.0.1:5099/api/remap/1.2/.
