chore(env): WEB_PORT 统一回退为 5173 并烟雾检查改为可开关

- .env.example/docker-compose(.full).yml WEB_PORT 默认值 5273→5173（Vite 默认），CORS_ORIGINS 同步
- docker-compose 注入 WEB_PORT/SERVER_PORT 环境变量，健康检查端口随之更新
- start.sh 新增 SERVER_SMOKE_CHECK_ENABLED 开关，默认关闭烟雾检查，仅健康探测
- web/web_start.sh 适配端口
- .gitignore 补充忽略 tmp/ 运行时目录
