Check a print's warm-up and rest where a print already runs

cloud.pause-resume runs a print end to end, which is exactly what the job
lifecycle needs to be seen: a non-zero hold before the first fire, a non-zero
rest after the park, and neither on the connect-time hunt in the same
session. Folding the checks in there costs the operator nothing, where a
test of its own would cost another print.

The forgetest replay noticed first: it plays a real captured log from a build
that predates those lines. Rather than editing what the machine said that
day, the replay carries the two lines where the current build emits them.

BRINGUP's cloud item now names what is actually open on the header keys, the
park and the two periods, and records that the pause constants were looked
for in the wrong place.
