Add mod_menu default override with showtitle; fix a11y/FAB overlap

- Create default.php for mod_menu with showtitle support, suitable
  for sidebar and footer menu modules (simple nav list, not navbar).
- Fix accessibility toolbar overlapping theme FAB by stacking the
  a11y toggle above the FAB instead of beside it.
