fix: 修复聚合模式下，名称带有中文或特殊符号的分享token判断异常的问题

1. 新增SUB_STORE_BACKEND_MERGE配置变量，支持功能整合模式：
   - 当设置SUB_STORE_BACKEND_MERGE为非空任意值时，后端支持同时处理API和前端资源请求
   - 新增配置示例：
     #合并前后端端口
     SUB_STORE_BACKEND_MERGE=true
     #设置接口安全地址
     SUB_STORE_FRONTEND_BACKEND_PATH=/safe-api
     #设置前端文件的路径
     SUB_STORE_FRONTEND_PATH=./dist
     #后端监听的端口
     SUB_STORE_BACKEND_API_PORT=3000
     #后端监听的HOST
     SUB_STORE_BACKEND_API_HOST="127.0.0.1"

2. 合并后支持前端在子路由界面刷新：
   - 原前端在subs、files、sync等页面刷新时会出现404问题，合并后修复了该问题
