k3s update bumped Traefik chart 37 → 39, dropping v2 support. Replace
the v2-only `whitelist.sourcerange` annotation on the gitea ingress
with an `ipAllowList` Middleware (resources/gitea-middleware.yaml),
referenced via `router.middlewares`. Switch the default-ns ingresses
(kube-plex, radarr, sonarr, lidarr) from the deprecated
`kubernetes.io/ingress.class` annotation to `spec.ingressClassName`.
