Surface held locks in the dashboard's work-in-progress widget

A lock with no draft or autosave behind it was invisible to
everyone including its holder, until the next editor collided
with it. work_in_progress now admits those nodes, and the
widget names the holder rather than the last editor on any
locked row.

Also flips the ordering to stalest-first, so a backlog reads as a queue
rather than a feed, and gives the heading a real total: the count came
from the already-limited relation and could never exceed five.
