Scooby Husky 85c916285e Phase 2: deploy n8n and Nextcloud warm standbys on the VPS
Same CNPG replica-cluster pattern as Authentik (continuous WAL replay
from home via VPS MinIO, app at 0 replicas until manual promotion - see
infrastructure/vps-standby/authentik/manifests/cnpg-cluster.yaml for the
full rationale).

n8n: N8N_ENCRYPTION_KEY copied byte-identical from home (kubectl, not
git) - decrypts stored credentials in the replicated DB, same reasoning
as Vault's unseal key / root token copies.

Nextcloud: adds infrastructure/vps-standby/nextcloud/manifests/
pvc-restore-cronjob.yaml, the read side of home's existing
nextcloud-pvc-sync restic backup - restores the latest snapshot from VPS
MinIO into this standby's PVC daily at 04:00 (2h after home's 02:00
backup). No Redis on the VPS side (no redis-operator deployed there,
out of scope for a standby that isn't serving traffic - Nextcloud
degrades gracefully to DB-based locking without it).

# n8n warm standby on the VPS - Phase 2. Same discipline as
# infrastructure/vps-standby/authentik/values.yaml: the CNPG replica
# cluster keeps the DB continuously warm in the background, but the app
# itself stays at replicaCount: 0 until a deliberate manual promotion
# (flip pg-n8n's spec.replica.enabled to false, then scale this up).
#
# N8N_ENCRYPTION_KEY must be byte-identical to home's - it decrypts
# stored credentials (API keys, OAuth tokens, etc.) that live encrypted
# in the DB being replicated. Unlike Authentik's chart-deterministic
# secret_key, n8n's isn't derived from anything reproducible - it's
# copied for real (kubectl, not git, same as Vault's unseal key /
# root token):
# kubectl -n n8n create secret generic n8n-config-secret \
# --from-literal=encryption-key=<home's N8N_ENCRYPTION_KEY>
