driveAtlas: silence SC2059 in generate_nuc_layout (ANSI-art printfs)

The NUC layout printfs intentionally embed our own DA_* ANSI colour vars and
literal box-drawing in the format string (no '%', device names passed as %s
args), so SC2059 is a false positive here. Scope a shellcheck disable to the
function to restore a green lint run.
