/**
 * Frontend tests for the AddNotificationModal — focused on the per-event
 * ntfy Priority section (#990).
 *
 * Coverage:
 * - Priority section renders only for ntfy provider type.
 * - Section lists ONLY events the user has enabled, not the whole catalogue.
 * - Save round-trips event_priorities into config.
 * - Editing an existing ntfy provider pre-fills priorities from config.
 * - Switching off a toggle drops the matching row from the priority section.
 * - For non-ntfy providers, event_priorities never appears in the saved config.
