连接状态（正式）： - /api/display/state 扩展：screens_online（大屏心跳统计，opc/display/heartbeat）+ last_command（最近指令与发布结果） - 前端大屏每 10s 上报心跳（稳定 client_id），后端 30s TTL 统计在线大屏数 - 管理台新增「连接状态」卡片：后端/MQTT/在线大屏/最近指令，3s 轮询刷新 按钮无响应根治： - admin.js 改为 document 事件委托（data-nav/data-control/data-action/复制/预览），不再依赖逐个绑定 - /static 与 /admin 响应加 no-cache 头，杜绝旧 JS/CSS 缓存导致的按钮失效 - SSE 不再自动重载页面（避免与操作回调双重重载清掉反馈）；立即播放改为 toast 不重载
