test(daemon-app): yield in the terminal-job wait like every sibling helper

app_wait_for_terminal_job_with_subscribers was the only app_wait_for_*
helper polling without cbm_usleep(1000): a sleepless spin pins a core for
up to 10s and can starve the daemon threads it is polling on scarce-CPU
runners. Release run 30305464193 hit exactly this on windows-11-arm
(test_daemon_application.c:2671 ASSERT(terminal_with_prior_subscribers));
the suite passes 47/47 locally with the yield in place.
