Notifications in groups, and what is unread

The Notifications tab reads grouped notifications (/api/v2/notifications):
likes and boosts of one post, or follows of one hour, are one card naming
both accounts of a pair, or the newest and how many others, with their
avatars. A notification the stream tells joins its group and waits on top.
The tab's badge counts what is unread; opening the tab moves the
notifications marker to the newest shown, which reads it on PrivaPub.
