4.4.2 Linux Debian 11 - rename folder and files in payload entering slash / in name cause creating erroneous subfolders

[slrslr]

qBittorrent & operating system versions

qbt 4.4.2 (appimage)
Linux Debian 11
qt 6.2.4
libtorrent 2.0.5.0

What is the problem?

Payload and on disk file/folder structure is broken when using slash in the payload folder/file names.

Steps to reproduce

Go downloading a torrent that in its payload structure has folder and several files in the folder.
Automatic management of the torrent.; Sequential download
Torrent download begin
Now rename that folder by entering: a / b
Rename also files:
c / d.ext
e / f.ext

i think that this slash (/) should cause qbt to damage the payload and on-disk folder structure.

#17049 Hope allowing remove the folder by renaming it to empty could be a solution for these folders that were created by mistake, instead of banning the character.
