feat(deploy): 完整 Docker 部署方案 — 寄卖商城 + 积分商城

新增两步独立 Docker 部署方案（czleilei240 环境）：

步骤一 寄卖商城（integral-resell）
- step1-integral/docker-compose.yml：redis(Alpine自建) + houtai(webman PHP8) + h5(Nginx)
- houtai.Dockerfile：PHP 8.0 + 阿里云镜像源 + webman.bin entrypoint
- h5.Dockerfile：Nginx + configs.js 环境变量动态重写
- redis.Dockerfile：Alpine + apk 构建，绕过 DockerHub 镜像源问题
- 宿主机 bind-mount：/www/wwwroot/leileiadmin.czchunfang.com（FTP可直接更新程序）

步骤二 积分商城（single-shop-22）
- step2-single-shop/docker-compose.yml：redis + admin-api + front-api + admin-web + h5
- Java Dockerfiles：OpenJDK 17 + --add-opens Spring Boot 2.2.6 兼容

公共配置
- nginx/：四个域名宝塔 Nginx 反代配置（HTTP→HTTPS 301、SSL 终止）
- scripts/：sync-to-server.sh / deploy-step1.sh / remote-up.sh
- DOCKER_DEPLOY.md：完整部署文档
