refactor: config/apps 目录重组、文档重构、架构图收窄

- 中央：config/(prometheus,alertmanager,grafana)、apps/(tile-cache,topology-editor) - 边缘：config/(vmagent,blackbox,targets)、apps/(onvif-exporter) - env: TRAEFIK_PROVIDER、prometheus/env.example 详细说明 - 文档：README/doc 重构，EDGE_CACHE 合并到 EDGE_AGENT_CONFIG - targets.csv 更新流程说明，ARCHITECTURE 图收窄 Made-with: Cursor
