feat: 添加后台统计页面

Browse source 
为项目增加了一个后台页面, 用于显示IP代理的使用情况统计.

主要包括:
- 新增 `backend` 目录, 包含 `index.html` 和 `script.js` 文件, 用于展示统计数据.
- 在 `main.go` 中增加了 `setBackendRoute` 函数, 用于提供后台页面的路由.
- 将后台页面路由设置为 `/admin`.

注意: 当前代码存在编译错误, 因为无法确定 `ipfilter.NewIPFilter` 的正确返回类型. 错误信息为 `undefined: ipfilter.IPFilter`. 提交此代码是为了让用户能够检查问题.
