fix: correct UUID extraction from nginx.conf after sb -d changes

* fix awk logic matching /auto and /auto2 instead of actual UUID path
* avoid empty UUID caused by incorrect regex matching fallback rules
* thanks https://github.com/github0null for reporting the issue

fix: 修复 sb -d 后 nginx.conf 中 UUID 提取错误问题

* 修复 awk 匹配到 /auto、/auto2 而非真实 UUID 路径的问题
* 修复正则错误导致 UUID 为空的问题
* 感谢 https://github.com/github0null 反馈该问题
