Replace disk-modifying chown/chmod with non-destructive accessibility check

Instead of modifying actual filesystem permissions on the mounted disk
(which would be destructive), we now only check whether the mount point
is likely inaccessible by the configured PUID and warn the user with
instructions to fix it themselves on the host.
