fix(traefik): persist plugin storage on a PVC

Mount traefik-plugins PVC at /plugins-storage instead of the chart default emptyDir, so the crowdsec-bouncer download survives node reboots. Without this Traefik starts before the network is ready, the download from plugins.traefik.io times out, plugins get disabled and every route behind the middleware returns 404/503 until a manual restart.
