Fix cache storage landing in ephemeral /tmp

Upstream joins STORAGE_PATH onto os.tmpdir() unless
STORAGE_PATH_USE_TMP_FOLDER=false, even for absolute paths, so the
container wrote artifacts to /tmp/app/cache instead of the bind mount
and lost them on every restart. Set the flag in both config.env
(native service) and the quadlet, and chown the host cache dir to the
container user via the :U volume option.
