Make OEM state world-readable for user-context finalization

The Node tarball in /var/lib/omarchy/oem/packages is read by
omarchy-finalize-user running as the freshly created user; a 0700 directory
forced the offline install onto its network fallback. The only secret inside
(luks-key) is itself 0600 root.
