r'''管理页 UI：加「允许新设备接入」开关 + 每台设备的「改码」按钮。

设计上遵守用户的"所有东西都要白色简洁"：
  * 开关用系统原生 checkbox + 极简样式，不引入花哨组件
  * 改码走 prompt()，不加弹窗层 —— 管理页是自用的，
    少一层 DOM 就少一处会坏的地方
  * 按钮沿用现有的 .ghost 样式（不抢 .danger 的视觉重量）

⚠ 一个容易踩的坑：
  现有 JS 用 `button.danger[data-device]` 绑定"单台删除"。
  新加的"改码"按钮**故意不带 data-device 而用 data-recode**，
  否则会被删除逻辑一起选中，点改码变成删设备。
