feat(discount): calculate_product_cost 接产品级折扣

折扣精确到 product_id（discount_detail.productid），三类折扣取最优惠(min)：
- 客户折扣 get_min_product_discount(pid, resellerid, customerid)
- 分销商折扣 get_min_distributor_discount(pid, resellerid, distributorid)
- 供应商折扣 get_min_supplier_discount(pid, resellerid, supplierid)
resellerid=product.org_id, supplierid=product.providerid,
distributorid 从 discount_customer_bind 按 customerid 查。
