Key Test Cases for This PR

Suite	Test Name	What It Validates
core	When called without external DNS, it should use LoadBalancer for APIServer	Non-Private topology defaults KAS to LoadBalancer (no regression)
core	When called with external DNS, it should use Route for APIServer	External DNS triggers Route strategy for KAS
azure	When endpoint-access is Private it should render HostedCluster with Private endpoint access	Private fixture includes `publicZoneID` (aligned with AWS behavior)
infra	Route strategy, Private without hostname — internal route only	CPO creates only internal KAS route when no hostname configured
infra	Transitioning from public to private should clean up public resources	Obsolete external routes deleted during topology transition
globalconfig	when DNS parameters specified then they are copied to the DNS object	Both `publicZone` and `privateZone` propagated to guest `dns.cluster`
