ipx-play's metrics on 9191: 9189 is hnopml's (#458)

5d0ff1a put ipx-play's /metrics on 9189, but hnopml, in the same
compose project, has published 192.168.1.130:9189 since 2026-11-12 and
Prometheus scrapes it there as job="hnopml". Deployed as written,
ipx-play's port would have clashed with it. 9187 to 9190 are ipx, the
directory, hnopml and ipx-web; 9191 is free.
