fix(nextcloud): Enable persistence to survive pod restarts

Nextcloud requires a persistent /var/www/html to retain installation
state (config.php, version.php, installed apps) across restarts.
Without it, every restart triggers the setup wizard. Uses local-path
2Gi PVC with Recreate strategy since the volume is RWO.
