The PeerRelay resource hardcoded UDP port 41641 in the generated
Service, the tailscaled config, status.endpoints and the advertised
static endpoints. That breaks deployments where the load balancer
address or port is not what peers can actually reach, e.g. behind NAT.
Add spec.service.port to choose the UDP port, and spec.staticEndpoints
to advertise extra address:port pairs alongside the discovered load
balancer endpoints. A replica whose only endpoint is a static one
counts as addressed, and a static entry's port wins when it names an
address the load balancer already provides.
The e2e tests now supply static endpoints, which lets them assert the
PeerRelayReady condition goes True in kind, where no cloud controller
ever gives the LoadBalancer Services an address.
