Small update on recent suggestion by paid2

How it works:
Once the order status switches to "COMPLETE," the user gets a message saying the exchange is done, followed by a question asking if they want to delete the ticket.
If they reply with "yes," the bot runs the /remove_order command using the saved order ID and deletes the ticket for uuser.
If they don’t reply, nothing happens. The bot just keeps the ticket in its memory until they start a new exchange or delete order manually
