Add service.kubernetes.io/service-proxy-name label to LoadBalancer
services when external: true. This prevents Cilium from adding the
service to its BPF service map, fixing two issues:
1. Inter-tenant connectivity via public LB IPs: Cilium's kube-proxy
replacement DNATs traffic to LB IPs before policy evaluation,
causing the CiliumClusterwideNetworkPolicy to block legitimate
cross-tenant traffic through public IPs.
2. WholeIP broken on Cilium 1.19+ (#2327): wildcard service drop
entries block all ports not declared in the Service spec before
traffic reaches cozy-proxy's nftables rules.
With this label, Cilium completely ignores the Service. Routing is
handled by kube-ovn (via the wholeIP annotation) and MetalLB
continues to advertise the IP via L2 unaffected.
Tested on Cilium 1.18.6 and 1.19.1: inter-tenant via LB IP works,
pod IP isolation preserved, external access unaffected.
