网络架构:
- iot-platform: host -> bridge (新增 -p 8887:8887 端口映射)
- taos-explorer: bridge (新增 /mnt/taos-explorer-data 数据持久化)
- tdengine-operator: 保持 host 网络

配置更新:
- TDengine URL: 127.0.0.1 -> 172.21.185.173 (宿主机内网 IP)
- Redis host: localhost -> ${REDIS_HOST:localhost} 环境变量
- taos.cfg fqdn: 127.0.0.1 -> 172.21.185.173
- explorer.toml cluster: localhost -> 172.21.185.173

部署脚本:
- REMOTE_DIR: /opt/iot-platform -> /mnt/iot-platform
- 日志目录: /opt/iot-platform/logs -> /mnt/iot-platform/logs
- 去掉自动回滚逻辑，保留容器用于排查
- 新增 -p 8887:8887 端口映射

新增服务器配置文件到仓库:
- deploy/Dockerfile
- deploy/start-container.sh
- deploy/config/taos.cfg
- deploy/config/explorer.toml
- deploy/config/tdengine-explorer.conf
- .env (移除 .gitignore 忽略)
