Create a global customer object atomically: Customer + DeliveryLocation + Contact + OpeningHours in a single API call. All validation is performed together. If any part fails, nothing is created (transactional). ⚠️ Limitations: Maximum 1 delivery location per customer, 1 contact per location, 2 time slots per location.
