The WEB_VIEW route recreated the WebView on every return from the
remote screen — full reload + re-login every time. The kiosk WebView is
now retained in a holder and reattached live (no race, no reload);
clients/bridges/listeners are re-bound to the new composition on
reattach, and the instance is dropped on retry, disconnect, or server
change so errored/stale sessions still reload for real.
