The lookup used to read local records only, so a visitor who paid after the
queue stopped watching saw "expired, no payment recorded". For a created
order it now runs the same read-only Stripe completion check the payment
window uses, records a confirmed payment on the order (and frees its window)
when the order lock is free, and says whether Stripe could be reached. It
still never creates orders or joins the queue; the lookup limit drops to 6
requests per minute per IP because each one may call Stripe.
