refactor: 边缘节点与配置精简

- 边缘: Prometheus 改为 vmagent，统一 docker-compose.yml，内存+磁盘缓存
- 边缘脚本: 合并为 deploy.sh [--local]，删除 run-edge-local、quick-setup、run-edge-with-cache
- 配置: 合并为 update-configs.sh，统一 targets.csv，生成 target-onvif/target-ping/target-topology
- 删除 topology-editor、旧格式 devices.csv/ping-targets.csv、setup-remote-write、test-connection
- 文档: 更新 EDGE_CACHE、TIANDITU（瓦片改 4090 直连 tile-cache）
