Подсказка external_id из уже увиденных устройств при добавлении

Поле External ID при создании/изменении устройства теперь input+datalist:
можно вписать значение вручную (как раньше) или выбрать из подсказок —
идентификаторы устройств, от которых device-control-service уже
получал MQTT-телеметрию/ack (Redis-множество devices:known), но
которые ещё не зарегистрированы в Postgres. Уже зарегистрированные
id из списка подсказок исключаются.

DeviceShadow::knownExternalIds() — новый read-метод (SMEMBERS
devices:known), зеркалит то же множество, что Go-сервисы уже читают/
пишут для health-check/online-детекции.
