Bug : 首页 Socks 配置，全局使用sing-box，最终生成的/tmp/etc/passwall/HTTP_SOCKS_7ZJoCsPC.json文件中final的值有误

[HenTele]

这条Socks 配置使用的是自定义接口（bind_interface）作为出口，配置了http入站和socks入站

如下是实际生成的/tmp/etc/passwall/HTTP_SOCKS_7ZJoCsPC.json文件
正确的final值（.route.final）应该为outbound。目前生成的json文件会导致socks服务启动失败

{
  "outbounds": [
    {
      "routing_mark": 255,
      "type": "direct",
      "bind_interface": "wireguard_out",
      "tag": "outbound"
    },
    {
