Step 2. Creates the order from get_quote's next.arguments (quoteId, plus to if the quote had none): one order per quote; moves no funds. Retry with the same arguments: the default idempotencyKey returns the same order.

`to`	No	Destination, only if the quote had none (next.missing). Never guess.
`detail`	No
