Story Crater Bot 68107ba962 fix(authentik): use 'app' database credentials from CNPG (GitOps)
GITOPS FIX: Permanent solution for database credentials

CHANGES:
  1. authentik-values.yaml:
     - postgresql.user: authentik → app
     - env vars reference ddb-cluster-app secret (via secretKeyRef)
     - Both server + worker containers updated

  2. sync-db-credentials-job.yaml (PostSync):
     - Copies ddb-cluster-app from ddb → iam namespace
     - Allows secretKeyRef to work (no cross-namespace support)
     - Runs after every iam-jobs sync

  3. kustomization.yaml:
     - Added sync-db-credentials-job to resources

REPLACES:
  - Manual kubectl patch of authentik-secrets
  - SOPS-encrypted per-app credentials
  - Complex permission grants

BENEFITS:
   ArgoCD won't revert changes (in git)
   Follows CNPG simple pattern (app user)
   Single source of truth (ddb-cluster-app)
   Auto-syncs on every deploy

Deployed by: iam-jobs Application (wave 3)
