Servers is a block in Administration, not a section of its own

It is the same KIND of thing as the root location and the databases — this
machine, not the site's content — and a nav row leading to one card was a whole
screen to reach three lines.

Last of the three, because it needs both of the others: a server has nowhere to
run without the checkout and nothing to read without a database.
