:::endpoint POST /v1/affiliates/pre-registrations/{id}/resend

Sends the original email again, with the same referral link and the same claim
code. Use this when the first email never arrived or was deleted.

## Request

```bash
curl -X POST https://api.proppertrading.com/v1/affiliates/pre-registrations/aff_pre_zd95p9x9prp3cga9thjusesr/resend \
  -H "Authorization: Bearer sk_live_a1b2c3d4_9f83c2e15b7a4d6e8091c3f5a7b9d1e2" \
  -H "Idempotency-Key: 3d1f0f2c-0a19-4b7e-9d21-77c5b2e4a801"
```

## Response

The reservation, with `last_sent_at` updated.

```json
{
    "data": {
        "id": "aff_pre_zd95p9x9prp3cga9thjusesr",
        "status": "pending",
        "last_sent_at": "2026-08-04T08:02:19+00:00"
    },
    "meta": { "request_id": "req_01kz4bkr1aj1gv63d8fv3133ey" }
}
```

The response does not contain the claim code. The email does.
