Add a reusable Dismissible helper that persists 'hide this permanently' state server-side in data/ui-state.json via the existing authenticated /read-file + /write-file endpoints. It's a direct file write — no task is created (nothing in the task manager) and no system scan runs — so it sidesteps the heavyweight config_update path entirely and works across browsers/devices. The backup config-backup warning now dismisses through Dismissible instead of localStorage; any future notice can opt in with Dismissible.isDismissed(id)/dismiss(id).
