nit-pick: comment is not really necessary, i.e., what vs. why comment
and has not much to do with the patch here.

why not just pass "-p" to scp (maybe we want to use rsync anyway, but if,
that's best left for another patch to do), then it tries to preserve some
metadata like mtime/atime and modes, so we probably just would need to ensure
that $tmpfile is readable and we'd be good to go.. For this, one could use
perl's builtin "chmod"[0], so we save a additional SSH connection (always good,
their not really cheap) and a run_command in the non-proxied part..
[0]: https://perldoc.perl.org/functions/chmod.html
also, the 'apl_download' call in pve-manager Nodes API perl module
does no special chmod or the like, AFAIS, could you take a look what
happens there, i.e., why's the permission already OK there? Does
wget downloads it to a world-readable file already? (this is more
out of interests sake)

my motto: conciser comments are better comments, they tend to less clutter
the code and be read more often :-)
maybe something like:
# best effort, to match apl_download call from manager, only
(just as idea)
