fix(fuse): umount (#15426)

Browse Source 
* fix(clipboard): clean up stale Linux FUSE mounts

Recover Linux file clipboard FUSE mount points before remounting and stop treating a cached
context as valid when the mount has already gone away.

This fixes the desktop file manager copy failure that shows dialogs such as
"Error while copying a" and "There was an error copying the file into xxx".

* fix: clear Linux file clipboard before unmounting FUSE

Ensure Linux client teardown clears RustDesk file clipboard URLs while
the FUSE context is still available. Also prefer fusermount before
umount to avoid noisy unprivileged teardown attempts.
