Add endpoint-agnostic Healthchecks pings to the three remaining scheduled
host-audit jobs via an EXIT-trap merge (start + success/fail), so the body of
each script (incl. the 1400-line daily-status-report) stays untouched. Exit
0/1/2 = ran (ok/warning/critical); only rc>2 pings /fail. Capability URLs come
from per-job host secret files (healthchecks_<job>_url), never in the repo.
bash -n verified.
