feat: per-kiosk auto-update toggle and app error reporting to superadmin Adds a per-kiosk-key auto-update opt-out (Admin -> Kiosk, piggybacked on the existing heartbeat) and forwards renderer console.error calls from paired kiosks into the existing platform_events log so they show up under Superadmin -> Aktivitas & Error, instead of only ever existing in that one machine's local app.log.
