Adds explicit UFW routed-allow rules (10.42.0.0/16 pod-to-pod, pod-to-Technitium
DNS) since these nodes default their routed/FORWARD policy to DROP. Also brings
nik-debian's NFS (2049) and SMB (445) ports under Ansible-managed UFW rules via
the existing nfs-server role, scoped to the Lab/Trusted networks that need them.
