Subject: [PATCH] feat(shared): add DmLastMessagePreview type with attachment
 metadata

Introduces a lightweight DmLastMessagePreview interface for the ready
payload and GET /api/dm response, and widens DmChannel.lastMessage to
accept either DmLastMessagePreview or DmMessageWithUser so both the
static preview path and real-time WS events can coexist without casts.
