Строгая типизация: TypeScript интерфейсы 1:1 с Pydantic-схемами

- Добавлен MemberBrief для вложенных объектов (author, assignee, reviewer, uploaded_by)
- Task.assignee/reviewer: Member → MemberBrief
- Message.author: Member → MemberBrief
- Step: добавлены task_id, created_at
- Task: добавлены created_at, updated_at
- Member: добавлен is_active
- ProjectFile: uploaded_by теперь MemberBrief вместо string
