cloud suite: a print turned away before the button fails at once, with the reason

The cloud client turns a print away before the button wait for four
reasons of its own (machine._safe_to_move): the lid or the interlock, a
machine that is not idle, the coolant above its start ceiling
(THERMAL.max_start_temp), a coolant sensor that reads nothing. It logs the
reason and finishes the print ':cancelled' within a millisecond. The four
tests that wait for the button looked only for the wait, so on the bench
reference, with the loop at 27.4 C against the ceiling of 27,
cloud.dark-print sat out its 120 s and said "the print never reached the
button wait".

wait_button_wait replaces the four waits: it ends on the print's finish
line as well, and fails with the client's own lines, for example "the
client turned the print away before the button wait: INFO
machine:_safe_to_move machine temp is too high, temp: 27.4 (... finished
with event ":cancelled")". The ceiling is the client's and stays where it
is: the remedy for a warm loop is airflow, a run session for a minute or
two.

Proven. test_a_print_turned_away_before_the_button_fails_at_once_with_the_reason
replays the bench reference's lines and fails in under 30 s with that
reason; with the early exit disabled it fails after the full 120 s with the
old words. Each reason is a line the pinned cloud library can log, so the
phrase check passes. The unit suite passes (422) with no undefined name. On
the bench reference, image 20260920211625 with this cloud.py over the
image's, cloud.dark-print passes through the new wait with the loop at
25.8 C.

Acceptance. cloud.dark-print, cloud.verdict-refuse,
cloud.lid-during-button-wait, and every test that starts an offline print
go through the new wait. The helper is module text, so every cloud.py
test's fingerprint moves; no product behavior changes.
