the first photograph leads, and nothing says so twice

A collection named its own main picture. A gallery is already ORDERED — somebody drags it into the
sequence they want — so "which one leads" was being answered twice, in two screens, by two mechanisms
that could disagree. Reordering a gallery and then wondering why the card had not changed was a bug
waiting to be filed.

So the grid here decides nothing at all. It is what the collection SHOWS, in the gallery's order, and
the pictures are no longer buttons: making them look pressable would promise a control that lives in
another screen. Adding, reordering and framing all belong to Galleries, and now so does this.

The `cover` column is gone from both databases.
