Simplify analytics/activity.html.

For legacy reasons, this template wanted each tab's content as
a one-key dictionary, instead of a string.  Each tab already has
a tuple to allow for fields like title, so this wasn't really giving us
any long term flexibility; it was just crufting up the calling
code.
