Remove the menu fold

The header menu no longer folds into a ☰ button: the nav_fold and
nav_fold_label options, Layout.Fold/BurgerAt, the burger markup and its
checkbox, the fold rules in blog.css and the measuring script on the
public page are gone, and the Design tab's preview only sizes its frame
again. The public page runs no script of its own once more.
