Menu item, address and page title — what the retired /fofos-admin/pages panel
held, moved to the column where everything else about that page is edited.
Above the device toggle, because the toggle scopes what is under it to one width
and none of these three have widths. Read from the URL rather than announced:
they belong to the page whatever is selected inside it, so picking a block must
not replace them.
A changed slug changes the page's own address, so the panel follows it — left
alone the URL would name a page the list no longer holds.
