GET /v1/orders returns newest orders first. Set limit from 1 to 100; the
default is 50.
When has_more is true, send next_cursor as the next request’s cursor
parameter. Treat the cursor as opaque and URL-encode it:
limit indexed rows for each page, regardless of the account’s total order
history.
A client_order_id lookup is not paginated. Send
GET /v1/orders?client_order_id=... to receive the normal page shape with zero
or one order and has_more: false. Do not send limit or cursor with that
lookup.
