web/satellite: remove unnecessary session inactivity timer setup

The dashboard area component would set up the session inactivity timers
after it was unmounted, conflicting with those that were started by
dashboards mounted afterward.

This issue caused session refresh requests to be sent more often than
they should have been. Additionally, expiration of the old set of
timers would clear newer ones before they were due to expire.
