feat(chat): личный чат тьютор ↔ админ с вложениями
Диалоги 1:1 (один тред на тьютора), отдельный SSE-канал whatido:chat вместо общей ленты notifications, вложения с белым списком расширений и вставкой из буфера (Ctrl+V), очистка по chat_retention_days. Таблицы в бэкап, chat_attachments добавлен в sweepOrphanedUploads.
