pad avatar bubbles to reflect true member count

Invite/request previews only carry the group owner's profile (convo.members
is only present for actual members), so AvatarBubbles only ever rendered the
owner plus a single placeholder. Add a `count` prop so the bubble pile reflects
the real member count, and use it for the invite card and the join/outgoing
request previews that were padding the profiles array by hand.
