refactor: UUID-based member refs in API types and components

- Task interface: assignee_id/assignee, reviewer_id/reviewer, watcher_ids
- Message interface: author_id/author вместо author_slug
- API functions: assignTask использует assignee_id
- KanbanBoard: обновлен под новые поля задач
- TaskModal: assignee selection по ID вместо slug
- ChatPanel: отображение author через relationship
