Function accept

accept(options: AcceptOrderOptions): Promise<void>
Accept an order

This function performs TWO critical operations:
1. Updates the order message's status field from INQUIRY (1) to ACCEPTED (2)
  - This hides the "Accept Order" button in the UI
2. Sends an order status update message to the customer
  - Shows "Processing" or "Confirmed" status
The order information is automatically retrieved from the message.
Parameters
- options: AcceptOrderOptions
Returns Promise<void>
Example
```
// Accept an order with default "Processing" status
await WPP.order.accept({
  msgId: 'message_id_here',
  acceptNote: 'Your order has been confirmed and is being processed'
});

// Accept with "Confirmed" status
await WPP.order.accept({
  msgId: 'message_id_here',
  orderStatus: WPP.order.OrderStatus.Confirmed,
  acceptNote: 'Your order has been confirmed'
});

// Accept without a note
await WPP.order.accept({
  msgId: 'message_id_here'
});
```
