arrstack: fix sync-wave deadlock + config multi-attach (#385)

## Why
The active-active arrstack deploy (#383) is stuck in-cluster: the app Deployments (sync-wave 0) can never become Healthy without their Postgres DB, so ArgoCD never advances to create the shared `arrstack-postgres` cluster (wave 1). Separately, `/config` is an immutable RWO cephrbd PVC, so 3 replicas fail with Multi-Attach.

## How
- Order DB infra before the apps: `<app>-db` VaultStaticSecrets + backup ObjectStoreUser/Bucket at sync-wave -3, CNPG `Cluster` -2, `Database` CRDs -1; app Deployments stay at default 0.
- Switch each app's `/config` to an emptyDir per-pod volume (library DB is in Postgres, config is env-driven; MediaCover regenerates). Old RWO config PVCs orphan.

Validated with kustomize build (62 resources). arrproxy/nzbget untouched.
