Update specific fields of existing orders. Only fields present in the request payload will be modified. Omitted fields retain their existing values. Use explicit null to clear optional field values.
Array fields (products, refunds, order_tags, discount_codes) are replaced entirely when present - no per-item merging is performed.
The entire batch fails if any order_id does not exist or any entry fails validation.
