Notifications card: show unread count bubble via the shared poll

pollNotifications now updates every .notif-badge (sidebar nav + homepage card)
from the same /api/notifications source, so the card bubble shows the unread
count and clears in lockstep with the sidebar. Add a badge to the card; scope
the collapsed-only badge positioning to the sidebar.
