feat(deploy): 阿里云ECS+1Panel 服务器部署方案落地

- docker-compose.server.yml:生产编排(复用 1Panel MySQL、去 mysql/redis、
  端口仅绑 127.0.0.1、TZ=Asia/Shanghai、MYSQL_HOST 必填守卫)
- 两份 Dockerfile 内置国内构建源:apt/pip→阿里云,npm/playwright→npmmirror
  (ECS 上直连官方源慢/超时;对本地构建同样可用)
- DEPLOY.md 重写为 v2 runbook:单站点反代架构、mysqldump+media 搬迁管道
  (ngram 索引导入重建 ~12min)、验收清单、运维表、本地停 scheduler 收尾
