-- name: AdminSummary :one
-- What the admin rail and the Overview's verdict read (#5605): each queue
-- that waits on a person, with how many and since when. One round trip, so
-- the rail costs one cheap read on every admin page. The "since" is the
-- oldest item still waiting: how long the queue has been left, which is what
-- tells the operator a count of 2 is fine today and wrong after a month.
