[F9/F10] 子系统管理 + 告警正交 5 态列表（UI 骨架 + mock）

两任务并行完成，因同动 router/iot.ts 与 locales/page.json 合并 commit。

F9 子系统管理 + 设备批量绑定:
- apps/web-antd/src/api/iot/subsystem/index.ts
- apps/web-antd/src/views/iot/subsystem/{list,form,devices}.vue
- apps/web-antd/src/views/iot/subsystem/__tests__/subsystem-utils.test.ts (18 用例)
- Known Pitfalls: 评审 A6 Redis stats 降级 / A7 403 拦截器 / 批量 100 台 / code regex snake_case
- 后端 B10/B11 API 契约: /iot/subsystem/{page,get,create,update,delete,simple-list,device-count}
  + /iot/device/{batchBindSubsystem,bindSubsystem} + /iot/device/page 加 subsystemId 过滤

F10 告警记录 (评审 C1 正交 5 态):
- apps/web-antd/src/views/iot/alarm/record/{list,detail}.vue
- apps/web-antd/src/views/iot/alarm/record/{alarm-state,api}.ts
- apps/web-antd/src/views/iot/alarm/record/components/{AlarmStateTag,AlarmOperations}.vue
- apps/web-antd/src/views/iot/alarm/record/__tests__/AlarmStateTag.spec.ts (12 用例)
- 5 态: 活跃·未确认(red) / 活跃·已确认(orange) / 已清除·未确认(gold醒目) / 已清除·已确认(green) / 已归档(default)
- Known Pitfalls: C1 5 态必展示 / archived 优先判断 / 30s 轮询 / 严重度颜色映射
- 后端 B12 API 契约: /iot/alarm-record/{page,get,ack,unack,clear,archive,batch-*,history,remark}

共同:
- apps/web-antd/src/router/routes/modules/iot.ts 追加 subsystem + alarm 路由
- locales/langs/{zh-CN,en-US}/page.json 追加 iot.subsystem.* + iot.alarm.*

note: 路由用顶级路径；项目采用动态菜单机制，菜单注册需后端 menu 表配置（运维侧工作）,
      前端路由可通过 URL 直接访问。
