Roll the verified Option-B per-app oauth2-proxy sidecar out to the remaining
four forward-auth apps after the pihole canary was confirmed fail-closed
(unauthenticated -> 302 to Keycloak, pod 2/2, clean sidecar OIDC discovery).
Each app's Gateway route now terminates at its oauth2-proxy sidecar (:4180,
--allowed-group=media-users, --upstream=http://127.0.0.1:<uiport>); the
gateway-ingress CiliumNetworkPolicy allows the Gateway to reach ONLY :4180, so
the bare UI is never served un-authenticated (fail-closed; R-IDP-02/06). The
apps' own app/API ports stay in-Service for EAST-WEST callers (arr ->
qbittorrent:8080 / jackett:9117) via the existing reciprocal-ingress allows.
- keycloak: confidential jackett/qbittorrent/radarr/sonarr clients (realm-import
+ realm-clients mirror), provisioned live via kcadm (groups membership mapper).
- secrets: four SOPS/age <app>-oauth2-proxy-credentials, wired into apps/wave-0
and apps/wave-1 by the renderer's sidecar-creds wave rule.
- ci: remove the temporary canary deferral (all five goldens now reproduce).
