- 新增 api/device.js（getDeviceList / getVitalSigns / getHeartRateHistory，
  当前 mock，后端就绪后关闭 USE_MOCK）
- 新增 components/vital-wave.vue 心率波形组件（canvas 自绘 ECG 风格面积图）
- 新增 pages/device/detail.vue ED713 体征仪表盘（心率大数字+波形、六指标
  +设备信息卡，加载/错误/重试三态）
- pages/index 设备列表改为双列卡片网格（loading/error/empty 三态，型号→图标映射，
  点卡片进详情页）
- pages.json / constants/routes 新增 DEVICE_DETAIL 路由注册，
  pages/scene/select up-navbar 启用 auto-back
