i had to move over scanner logic to its own module last time,
so i commented out the stats entry as i was cleaning it up, but forgot
to re-add it after finishing it
for context, we prefer to list files in zips dir, because admins may
choose to manually delete their ZIPs anytime, and lolisafe will not be
aware of it
the download API will automatically re-generate them if required, so
admins manually deleting ZIPs is okay
