Once organizations existed, Quick Setup was reachable only through
Settings > Organizations > type an ID > New organization. This tree
has no header organization switcher, so the owner of a Console with
organization setup now gets "New organization" in the header avatar
menu, under the Organization picker on Settings > Organization, and
next to the Settings link in the no-organization empty state. Each
opens #/settings/organizations?new=1, which focuses the ID field and
then drops the flag. The form itself is unchanged.
The new browser test covers the menu at 1400 and 390px, the picker
and the empty state. It fails on 6ca7f3b65 and passes here.
