audiobooks moved off the Cloudflare tunnel to the NetBird reverse proxy
(#36 removed the external-dns label). Remove the now-dead tunnel ingress
rule so cloudflared no longer advertises a route for it.
Note: cloudflared subPath-mounts this ConfigMap and does NOT auto-reload
— a rollout restart of the cloudflared Deployment is needed to apply.
Functionally moot once the orphaned Cloudflare DNS record is deleted.
