Module detail and index Run/Dry run buttons no longer redirect to the
run page. The status cell (index) and recent runs panel (detail) poll
every 3s while running and stop automatically when idle. force_poll
ensures polling starts immediately after clicking Run despite the race
between the HTTP response and the background task setting running=1.
