Add: AttributeType system_flags

[milov-dmitriy]

Для задачи по геораспределению необходимо понимать, какие атрибуты реплицируемы, а какие нет.

Для каждого Типа атрибута добавлено свойство system_flags (aka systemFlags в AD см.доку):

• добавлена миграция;
• доработана соответствующие AttributeType: DTO, Schema и Entity;
• для работы с system_flags у сущностей AttributeType добавлен отдельный UseCase.

Открытые вопросы:

• Нужно ли определять AttributeTypeSystemFlagsUseCase в AttributeTypeUseCase ?
  p.s. На данный момент эта бизнес логика нигде не используется. Кажется, что это избыточная модификация.
• ..UseCase для AttributeTypeSystemFlagsUseCase это подходящий выбор?
  p.s. Мне не нравится использование одного UseCase внутри другого UseCase. Как я думаю, в теории было бы правильно делать отдельный UseCase в котором была бы работа только с AttributeType и с AttributeType.system_flags.

Задача: 1160

Pull request overview

This PR adds support for the system_flags attribute to AttributeType entities to enable identification of replicable vs non-replicable attributes for geo-distribution. The implementation follows the Active Directory systemFlags specification and includes a dedicated UseCase for managing system flags.

Changes:

• Added system_flags integer field to AttributeType entities, DTOs, and schemas with a default value of 0
• Created migration to add the column and populate non-replicated attributes based on AD specification
• Implemented AttributeTypeSystemFlagsUseCase with methods to check and set replication flags
• Added integration methods in AttributeTypeUseCase that delegate to the system flags use case
