Subject: [PATCH] fix: preserve kube-vip mount path and only swap hostPath to
 super-admin

The previous replacement changed both mountPath and hostPath, causing kube-vip to lose its expected in-container kubeconfig path and exit. Keep mountPath at /etc/kubernetes/admin.conf, swap only hostPath during bootstrap, and enable kube-vip debug log level.
