/**
 * Approval-queue notify-failure path (real PGlite runtime, #12273).
 *
 * Enqueue surfaces a pending approval on the notification rail as a
 * fire-and-forget side-channel. This drives a NOTIFICATION service whose
 * `notify` rejects and asserts the failure is now reported via
 * `runtime.reportError` (scope `ApprovalQueue.notify`) instead of being
 * swallowed by a bare `.catch(() => {})`, while the enqueue itself still
 * succeeds (the persisted approval row is unaffected).
