feat: 蓝牙血压计BLE数据同步 + 设备管理页重构 + 健康记录滑动删除 + 医生端合并设计文档

Browse Source 
- BLE: 修复Omron设备Indication模式连接(先订阅后配CCCD + forceIndications) + 直连重连
- BLE: 设备断连实时检测(connectionState流→Provider→UI)
- 修复: 血压数据上报后端枚举不匹配(Device→DeviceSync)导致500
- 新增: DELETE /api/health-records/{id} 后端接口
- 设备管理页: 白色主题重设计 + 直连重连 + 实时状态 + Toast通知
- 设备扫描页: 白色主题 + 扫描动画居中 + 已连接等待页面
- 健康记录: 左滑删除(Dismissible) + 同时清理_allRecords和_filtered
- 导航: 修复自定义路由栈下Navigator.pop黑屏bug
- 文档: 医生端合并App完整设计文档(已确认版)
