feat(immich): scaffold registry manifests for postgres/redis/server (not yet live)

immich becomes a manifest-driven stack (the legacy install_immich_stack — hardcoded
podman run + sudo chown — is the anti-pattern being retired). Three image-only
manifests modelled on the btcpay stack + the live .228 container config:

- immich-postgres / immich-redis / immich-server on archy-net; container_name set
  to the underscore form (immich_postgres/_redis/_server) so the server's
  DB_HOSTNAME/REDIS_HOSTNAME aliases resolve.
- generated_secrets: [immich-db-password] (idempotent — reuses the live secret on
  existing nodes; postgres is already initialised with it).
- server depends on postgres+redis (install ordering); upload bind preserved.

Inert for now: not added to the UI catalog and install_immich_stack still the
default, so nothing installs these until the orchestrator wiring + on-node
ownership (data_uid) validation lands. Schema validated by the all-manifests
round-trip test. See docs/PRODUCTION-MASTER-PLAN.md §6.
