新增消息已读状态

复用 chat_participants.last_read_at 推导已读,无需新表/迁移。

- 后端:MessageDTO 增加 is_read,toMessageDTOs 按「全部已读」语义计算
  (所有其他参与者均已读才算已读,1对1 即对方已读);MarkRead 成功后
  推送 conversation_read 事件(含 reader 与 read_at),NotifyConversation
  与 NotifyAllAdmins 双通道通知,使发送方/客服实时刷新已读
- 前端:ChatMessage 增加 is_read,ChatView/AdminChatsView/MobileChatView
  在自己的消息下渲染「已读/未读」;收到 conversation_read 且本端仍有
  未获回执的自己消息时才重载,避免无谓请求
