KubeVirt page is not helpful or outdated regarding cluster isolation

If you are not a KKP developer, it's very hard to understand the network isolation model for KubeVirt from https://docs.kubermatic.com/kubermatic/v2.23/architecture/supported-providers/kubevirt/kubevirt.

I identified the following problems from a user perspective:

• The cluster isolation concept is not explained in a way that users are informed about it. The warning box at https://docs.kubermatic.com/kubermatic/v2.23/architecture/supported-providers/kubevirt/kubevirt/#configure-kkp-with-kubevirt is not enough since it does not explain how the cluster isolation works, nor does it give actionable examples for custom network policy configuration.
• The option to disable the cluster isolation network policies is not documented.
• I believe https://docs.kubermatic.com/kubermatic/v2.23/architecture/supported-providers/kubevirt/kubevirt/#i-created-a-load-balancer-service-on-a-user-cluster-but-services-outside-cannot-reach-it is completely out of date now and needs to be removed.

Start with the KubeVirt documentation page and the “Configure KKP with KubeVirt” and load-balancer sections linked in the issue. Verify the current cluster-isolation behavior and configuration options in the surrounding documentation, then update the explanation with actionable network-policy examples, document how to disable isolation, and remove the outdated load-balancer section.
