feat(alarm): 设备报警监控报警提示升级与警灯交互优化 - 报警提示升级：后端新增报警派单完成接口 POST /api/worker-app/alarm-dispatches/:id/complete（供共享电工APP确认完成，归属校验403/不存在404/已完成幂等，status置1并写completed_at）；GET /api/device-alarms 的 summary 由 severeIds 改为 activeSevereIds（grade=1 且无已完成派单的报警id，倒序100条，派单完成自动移出即报警取消）并新增轻量接口 GET /api/device-alarms/active-severe；前端新建全局悬浮立体警灯组件 AlarmSirenLight（红蓝双色3D警灯，挂载主布局所有页面可见，点击跳转报警监控页，30秒轮询activeSevereIds新id即时响+每3分钟重复响，Web Audio合成警笛700/900Hz交替，浏览器自动播放静默降级）；index.vue 移除原10秒指示灯与880Hz beep、瘦身为纯列表页；警灯交互优化：警灯可鼠标拖动（位移>5px判为拖动不触发跳转）、位置经localStorage跨刷新记忆（默认右上角）、取消「重置报警提示」按钮；后端tsc与前端vue-tsc编译通过，接口实测派单完成排除逻辑生效，浏览器端到端验证通过（全局显示、点击跳转、拖动、刷新记忆、重置按钮无残留）
