feat(web): IoT + FHIR V1 Plan 5 — Web 前端实施

- API 层: deviceReadings 日聚合查询 + OAuth 合作方 CRUD 接口
- 常量: 设备连接状态/连接类型/实时监控指标常量
- Hook: useVitalSSE — 复用全局 SSE 连接的 vital_update 事件
- 页面: RealtimeMonitor 实时体征监控台 (SSE + 告警排序)
- 页面: OAuthClientList FHIR 合作方管理 (CRUD + Secret 重置)
- 增强: DeviceManage 设备状态/固件/连接类型列 + 状态筛选
- 路由: 新增 3 个懒加载路由
- 测试: RealtimeMonitor + OAuthClientList 单元测试
