Summary of Changes

Hello @Bainianzzz, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

此拉取请求主要实现了超级管理员获取所有用户列表的功能，并通过引入新的API端点和客户端方法来支持这一操作。同时，对现有的身份校验装饰器进行了增强，以提高安全性，确保只有经过认证的根用户才能执行敏感操作。

Highlights

• 新增超级管理员获取所有用户功能: 为超级管理员引入了 list_user 方法，允许其分页获取系统中的所有用户。
• 优化身份校验装饰器: @self_hosted("root") 装饰器增加了额外的校验逻辑，确保只有已认证的根用户实例才能执行特定操作。
• 新增后端用户列表API: 在 swanlab/core_python/api/user/self_hosted.py 中添加了 get_users 函数，用于调用 /self_hosted/users 接口获取用户列表。

Code Review

This pull request introduces a new feature allowing a root user to retrieve a list of all users. It also includes a refactoring of the @self_hosted decorator to centralize permission checks. The implementation of the user listing is sound, using pagination to handle potentially large numbers of users.

My review focuses on improving the clarity, maintainability, and correctness of the new code. I've pointed out a misleading docstring and a hardcoded value in the new list_user method. More importantly, I've identified a potential logic issue in the updated @self_hosted decorator that could lead to unintended behavior. Finally, I've suggested adding a docstring to the new get_users helper function for better documentation.
