fix(ci): label cockpit workflow pods part-of=argo-workflows so MinIO ingress admits them → logs ARE archived

Root cause of months-long missing CI logs: MinIO's ingress netpol allows part-of in {foxhunt,foxhunt-ci,
argo-workflows}; the cockpit build/deploy pods carried neither label → MinIO denied the wait-sidecar's
log upload (i/o timeout) → builds errored. Using 'argo-workflows' (not 'foxhunt') admits them to MinIO
WITHOUT triggering argo-base-egress (which would block registry:5000/git:2222). Reverts the earlier
archiveLogs-disable approach — logs are now SAVED, not skipped.
