Add a "Remind silent" button to the bench attendance sheet

On-demand version of send_deadline_reminders' own NO_RESPONSE nudge, same
title/body shape, for a coach who doesn't want to wait for that once-a-day
sweep. Shown only when there's someone silent to remind, and only to whoever
manages the team.
