feat(2): Q3.2 lasuite-drive base enrollment + nested-subdomain + replicas:0 harness fixes

- harness: services_converged treats replicas:0 one-shot (minio-createbuckets) as
  converged (cur==want); removes the want==0 rejection that hung deploys. DECISIONS.md.
- recipe_meta.EXTRA_ENV flattens MINIO_DOMAIN/COLLABORA_DOMAIN to single-label wildcard
  siblings (the *.ci.commoninternet.net cert covers one label only). DECISIONS.md.
- lifecycle overlays (install/upgrade/backup/restore) + ops.py postgres ci_marker
  data-integrity (db user/name=drive). Parity health_check functional test. PARITY.md.
- DEPS=[keycloak] + OIDC/WOPI/upload functional tests deferred to the SSO iteration
  (probe-before-assert: prove the ~10-service base deploy converges first).
