Five modules keep their own secrets from the vault, under local names; route-proxy declares its bases

gitea, umami, influxdb, icecast and mailu require a secret and keep each of theirs
under a local name (novox/hq ADR 0094); the broker account stays their own. The
route proxy's recipe starts FROM the bases its manifest declares (ADR 0097).
