nuxt-oidc-auth persists sessions via useStorage('oidc'), whose default
mount is per-pod memory — broken at >1 replica (random 401s) and every
deploy logged all users out. A nitro plugin now mounts 'oidc' on the
dezky-data Redis (db 1, app-prefixed keys, 14d TTL) when SESSION_REDIS_URL
is set; dev keeps the memory driver with no Redis required. Replicas back
to 2 for both apps.
