fix: prevent VM detail page hang when static IP assigned (#1072) (#1073)

Make syncStaticIpAnnotations idempotent so it no longer mutates VM
annotations when already in sync, breaking a reactive update loop that
froze the browser on the VM detail page. Also stack multiple IP
addresses vertically in the IP Address column.
