Scheduled: where a task runs (runs_on), and choosing a linked computer in the form

The task page says the computer, folder, mode and approval wait, and whether
the computer is away or does not accept scheduled work (/devices
`scheduled`); a run waiting for it says so. The form offers Where it runs
where the server's devices say whether they accept, sending runs_on.
