feat(form): x-references поля → SingleSelect с опциями из target словаря

Поля spacecraft.status, satellite_type_code и другие FK с x-references
теперь показывают dropdown с записями из целевого справочника вместо
свободного ввода. Label формируется как '<code> — <name.ru-RU>' если
target имеет localized name.

Fallback на TextInput когда target dict недоступен (scope-hide → 404)
или пуст — admin может ввести значение вручную, валидация серверная.

Кеш 5 минут (referenced data slow-moving) через TanStack Query.
