Convert only-office, n8n, de-spiegel to nox modules

Mirror the proven converted modules: pure manifests, no runtime.

- only-office: owned onlyoffice/documentserver container, generated JWT
  own-secret, public route office.novox.be. Analog: gitea/hello-web.
- n8n: consumes mesh postgres-database + redis-cache providers instead of
  bundling them, owned container, public route n8n.novox.be. Analog:
  baserow (postgres+redis) + hello-web (route).
- de-spiegel: owned container built from its own repo image, public route
  de-spiegel.novox.be, given SMTP own-secrets. Analog: hello-web/invoicing.
