intl(dates): use moment for timeAgo and timestamps

This removes the internal timeAgo and uses moment's localized fromNow.  It also shows the tooltip timestamp localized as moment.format('LLLL zz') with the chosen language in the settings.  This branches off @ahdinosaurs prior art in #1206 and implements it across the codebase.  Also removes the human-time requirement.
