fix: resolve empty directory migration failure

1. Root cause: getTransferJson() only added top-level user-selected
   items to user_file array, never recursively enumerating empty
   subdirectories; setFile() path truncation from commit a05c2ff
   further broke deep directory source path construction
2. Fix: recursively enumerate empty subdirectories in
   getTransferJson() and add them to user_file array; remove path
   depth truncation in setFile() and restore correct source path
3. Impact: empty directories at any depth now migrate correctly;
   no behavior change for files and non-empty directories

Log: fix empty directory migration failure during backup import

Influence:

1. Test backup and restore with empty directories at various depths
2. Verify files and non-empty directories still migrate correctly
3. Test cross-device migration with empty directories

fix: 修复数据迁移时空目录无法迁移的问题

1. 根因：getTransferJson() 仅将用户选中的顶层项加入 user_file
   数组，未递归枚举空子目录；setFile() 中 a05c2ff 引入的路径
   截断逻辑进一步破坏了深层目录的源路径构造
2. 方案：在 getTransferJson() 中递归枚举空子目录并加入 user_file
   数组；移除 setFile() 中的路径深度截断逻辑，恢复正确的源路径构造
3. 影响：任意深度的空目录现在都能正确迁移；对文件和非空目录无行为变化

Log: 修复备份导入时空目录无法迁移的问题

Influence:

1. 测试不同深度空目录的备份与恢复
2. 验证文件和非空目录仍能正常迁移
3. 测试跨设备迁移场景下的空目录处理

Summary by Sourcery

Restore empty directories correctly during data migration without changing handling for files or non-empty directories.

Bug Fixes:

• Fix migration and backup restoration of empty directories at arbitrary nesting depths.
• Preserve complete source paths so deeply nested files and directories are restored to the correct locations.

Reviewer's Guide

The PR fixes empty-directory migration by adding recursively discovered empty subdirectories to the transfer manifest and removing restore-time path truncation, allowing directories at any depth to migrate while preserving existing file and non-empty-directory behavior.

File-Level Changes

Change	Details	Files
Recursively include empty subdirectories in the transfer manifest so backup/import can recreate them at arbitrary nesting depths.	Traverse selected directories with QDirIterator. Detect directories with no entries and append normalized home-relative paths to user_file. Avoid duplicate manifest entries.	src/plugins/data-transfer/core/utils/transferhepler.cpp
Preserve complete manifest paths when restoring files and directories instead of truncating them by depth.	Remove the two-level path filtering from setFile(). Construct the source path using the full manifest-relative path while retaining the target path under the home directory.	src/plugins/data-transfer/core/utils/settinghepler.cpp
