Hide potentially invisible DO Disclosures by default

Hiding/unhiding a pref triggers an animation. DO Disclosures that may
not be visible should be hidden by default so that they fade in if
applicable, not fade out if not applicable.

Also, the network and security logging disclosures should only be shown
if logging is currently on or was on in the past and a network log was
retrieved at least once.
