Bug Description (required)

调用 /api/share/create 接口为已经存在的文件夹创建分享时，API 始终返回 400 错误，提示 must add at least 1 object，即使该路径下已有文件。

复现步骤：

1. 使用有效的管理员 Token 进行认证（Authorization 头直接传 token，不加 Bearer 前缀）
2. 调用 /api/fs/mkdir 创建测试目录，例如 /OneDrive/test-folder
3. 调用 /api/fs/put 向该目录上传一个测试文件（mkdir 和 put 均返回 200）
4. 调用 /api/fs/list 验证文件已存在（返回文件列表，确认文件已上传）
5. 调用 /api/share/create，请求体为 {"paths": ["/OneDrive/test"]}
6. 返回 {"code":400,"message":"must add at least 1 object","data":null}

尝试过的变体：

• paths 数组形式：{"paths": ["/OneDrive/..."]}
• path 单数形式：{"path": "/OneDrive/..."}
• 相对路径形式：{"paths": ["/test-folder"]}
• 有文件的路径 vs 空文件夹路径

所有尝试均返回相同的 400 错误。

预期行为：
API 返回 200 状态码，并成功创建一个分享链接（返回 {"code":200,"message":"success","data":{"id":"xxx","url":"xxx"}}）

实际行为：
API 返回 {"code":400,"message":"must add at least 1 object","data":null}
