Adds permissions claim + per-service admin groups in Authentik, scoped
Role/RoleBinding per service, public PKCE kubernetes OAuth2 client, and
kube-apiserver OIDC extraArgs. Also fixes paperless OIDC signup permissions
via adapter override and adds CoreDNS rewrite for authentik.riotpiao.com.
Service "paperless" made k8s inject PAPERLESS_PORT=tcp://<ip>:8000 as a legacy Docker-links env var, which paperless-ngx's own entrypoint also reads for gunicorn's bind port - collided, gunicorn crash-looped ("not a valid port number"), and the pod was 1/1 Running with nothing actually listening (nginx saw 502).
Fixes controlplane.tftpl's install.wipe:true (should be false, live CPs already run false) and syncs coredns Corefile back to what's actually deployed (drops an unrolled-out, stale Kong-era rewrite).
