 * Label a stored event in Amazon Fraud Detector — the effectful feedback
 * call made from a deployed Lambda or Task when ground truth arrives (e.g. a
 * chargeback confirms fraud). Labeled events improve future model training.
 *
 * ### Labeling Stored Events
 * Provide the `UpdateEventLabelHttp` implementation layer on the Function
 * effect, bind the event type in the init phase, then call the returned
 * client at runtime. The binding grants `frauddetector:UpdateEventLabel` on
 * the event type and injects its `eventTypeName` automatically.
 *
 * **Example:** Label from a Lambda
 * ```typescript
 * // init
 * const updateEventLabel = yield* FraudDetector.UpdateEventLabel(eventType);
 *
 * return {
 *   fetch: Effect.gen(function* () {
 *     // runtime — a chargeback arrived for this order
 *     yield* updateEventLabel({
 *       eventId: "order-123",
 *       assignedLabel: "fraud",
 *       labelTimestamp: new Date().toISOString(),
 *     });
 *     return HttpServerResponse.json({ ok: true });
 *   }),
 * };
 * // on the Function effect:
 * // .pipe(Effect.provide(FraudDetector.UpdateEventLabelHttp))
 * ```
