/**
 * Store an event in Amazon Fraud Detector without generating a prediction —
 * the effectful ingestion call made from a deployed Lambda or Task. Stored
 * events build the historical dataset used to train models and can be
 * labeled later via `UpdateEventLabel`. The bound event type must have
 * `eventIngestion: "ENABLED"`.
 *
 * ### Ingesting Events
 * Provide the `SendEventHttp` 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:SendEvent` on the event type
 * and injects its `eventTypeName` automatically.
 *
 * **Example:** Ingest from a Lambda
 * ```typescript
 * // init
 * const sendEvent = yield* FraudDetector.SendEvent(eventType);
 *
 * return {
 *   fetch: Effect.gen(function* () {
 *     // runtime
 *     yield* sendEvent({
 *       eventId: "order-123",
 *       eventTimestamp: new Date().toISOString(),
 *       entities: [{ entityType: "customer", entityId: "cust-1" }],
 *       eventVariables: { email: "buyer@example.com", ip: "1.2.3.4" },
 *     });
 *     return HttpServerResponse.json({ ok: true });
 *   }),
 * };
 * // on the Function effect:
 * // .pipe(Effect.provide(FraudDetector.SendEventHttp))
 * ```
