refactor(fs): batch remove and rename

[jenken827]

很多网盘原生支持批量重命名和删除，但是目前openlist对于这两种操作是通过循环调用单次重命名和删除实现的，量大时效率非常低下，还容易导致失败（有些api有调用频率限制）。
修改点如下：
1.支持了原生批量重命名和删除
2.文件相关操作有大量重复的对于path的解析及鉴权代码，优化集中到中间件中
3.修复在批量重命名选择序列模式（第二个模式）时，如果文件本身没有扩展名，重命名后会多出一个"."的问题（前端）

Pull Request Overview

This PR refactors file operations to support native batch rename and remove operations instead of using inefficient loops, while centralizing path validation and authentication logic in middleware.

• Adds support for native batch rename and batch remove operations through new driver interfaces
• Consolidates duplicate path parsing and authentication code into reusable middleware functions
• Implements batch operations for Baidu Netdisk and 123 Open cloud storage drivers
