Read results once a minute

Browse Source 
Every read of results asks each video schedule for its drafts, and the
dashboard read them every 10s while anything was being made, so the
network tab filled with video-drafts requests. Poll once a minute on the
dashboard and Results page, and reuse a read under a minute old when a
page opens or regains focus. Actions still refresh results at once.
