Subject: [PATCH] fix: Change listType from SINGLE_SELECT to PRODUCT_LIST to
 match pastorini

Error 479 was still occurring even with legacy listMessage format.
The issue is that listType must be PRODUCT_LIST (not SINGLE_SELECT)
to match the biz node type="product_list" v="2" that we're injecting.

This matches pastorini's working implementation exactly:
- listMessage with listType: PRODUCT_LIST
- biz node with type="product_list" v="2"
