Phase 1 #21 #22 #25 #26: GIS + IoT + DevOps + Notify

#21 GIS 引擎集成:
- GeoServer init 脚本（自动创建工作区/数据源）
- Leaflet 地图组件 (Vue3 MapView: 点位/弹窗/OSM底图)
- GisService: PostGIS 空间查询(附近设备/片区统计/GeoJSON)
- GisController: /nearby /device-stats /geojson API

#22 IoT 设备接入层:
- Kafka Consumer: iot.telemetry + iot.event 消费
- DeviceController: 设备列表/详情/注册/指令下发 REST API

#26 消息通知:
- NotifyService: 短信/WebSocket/APP Push/多渠道分发
- NotifyController: SMS/Push API

#25 DevOps:
- 10个微服务 Dockerfile (Eclipse Temurin JRE17)
- CI build.sh: Maven构建 + Docker镜像打包
- Frontend Nginx 反向代理配置
