fix: show filename during file transfer progress

1. Root cause: IPC FileStatus struct already carries filename in
   param.name (full filepath from daemon), but three frontend handlers
   (TransferHelper, CooperationProxy, MainController) parsed progress
   data and ignored param.name, leaving UI with no filename display
2. Fix: extract filename via QFileInfo(param.name.c_str()).fileName()
   in all three onFileTransStatusChanged handlers, pass through
   updateProgress chain to TransferDialog, CooperationTransDialog and
   system notification respectively
3. Impact: all updateProgress/setProgress/updateProgressData signatures
   gain filename param with default QString(), existing callers
   unaffected; new fileNameLabel added to TransferDialog and
   ProgressWidget UI

Log: Show current transferring filename in progress dialog and notification

Influence:

1. Test file transfer from UOS to Windows, verify filename shown
2. Test file transfer from Windows to UOS, verify filename shown
3. Test batch transfer, verify filename updates per file
4. Verify notification shows filename when receiving files
5. Verify empty filename falls back to original progress display

fix: 文件传输过程中显示当前传输文件名

1. 根因：IPC FileStatus 结构体已通过 param.name 携带文件名（daemon 填充
   完整路径），但三个前端处理函数（TransferHelper、CooperationProxy、
   MainController）解析进度数据时忽略了 param.name，导致界面不显示文件名
2. 方案：在三个 onFileTransStatusChanged 处理函数中通过
   QFileInfo(param.name.c_str()).fileName() 提取文件名，经
   updateProgress 调用链传递至 TransferDialog、CooperationTransDialog
   和系统通知
3. 影响：所有 updateProgress/setProgress/updateProgressData 签名新增
   filename 参数并使用默认值 QString()，现有调用者不受影响；
   TransferDialog 和 ProgressWidget 界面新增 fileNameLabel 控件

Log: 传输进度界面和通知中显示当前传输的文件名

Influence:

1. 测试 UOS 向 Windows 传输文件，验证进度界面显示文件名
2. 测试 Windows 向 UOS 传输文件，验证进度界面显示文件名
3. 测试批量传输，验证文件名随当前传输文件动态更新
4. 验证接收文件时系统通知显示文件名
5. 验证文件名为空时退化为原有进度显示

Summary by Sourcery

Show the active filename throughout file-transfer progress reporting while retaining existing behavior when filename data is unavailable.

New Features:

• Display the current filename in transfer progress dialogs and receiving-file system notifications.

Bug Fixes:

• Restore filename propagation from file-transfer status updates so filenames appear during individual and batch transfers.

Enhancements:

• Preserve the existing progress display when no filename is available and elide long filenames for readable presentation.
