feat(alarm): ICC 报警事件订阅与设备报警监控/报警派单 - 重建 device_alarm 表（迁移20261024_icc_event_alarm.sql：alarm_code 唯一、uuid、line 关联、客户、等级、事件标记、alarm_time 等 19 字段与 4 索引）并新建 alarm_dispatch 派单表（15 字段）；订阅服务 IccEventSubscribeService 复用 OAuth2 鉴权向 ICC 注册报警事件回调（POST subscribe/mqinfo，monitor 带 token、同名覆盖保活），每 30 分钟保活任务（sys_job 种子）；回调 POST /api/icc-event/callback 无鉴权仅 URL token 校验，兼容单条/数组事件解析、按 alarmCode 幂等 upsert、匹配 electric_line.line_code 回填线路客户；新增 GET /api/device-alarms（列表+今日/严重/未派单统计+客户/等级/关键词筛选）与 POST /api/device-alarms/:id/dispatch（AD 派单号、同报警重复派单拦截、电工在岗审核校验、NoticeService 站内通知）；GET /api/alarm-dispatches 台账（联电工/客户名）；前端设备报警监控页（统计卡/筛选/表格/发起报警派单弹窗/30 秒轮询+严重报警红灯闪烁与 Web Audio 蜂鸣/订阅状态弹窗）与报警派单台账页+路由；菜单 63/64、role_menu、sys_job 种子；同步 db_init/db_seed 与设计文档；端到端验证通过
