Enrolling ace applied adoption.opening-tcp-5671-incoming to it, opening
5671 from anywhere (v4+v6) where nothing listens — the ace session
caught it. foundation ports widen the broker's from:mesh port to
from-anywhere so a machine that is not yet on the mesh can make its
first dial; that belongs on the broker's host alone. foundationPortsFor
keeps the port only when a module resolved onto this node listens on
it, so novox opens 5671 and a node that merely dials out opens nothing.
Two tests, both directions.
