fix(cfc-backend): 迁移33 供应商分销体系(4新表+product_orders 3列)

- 迁移33: 创建supply_system/supply_system_member/supply_settlement/
  supply_settlement_detail 4张表 + product_orders追加supply_system_id/
  supplier_id/supply_commission 3列+索引
- schema.sql: product_orders补列 + 追加4张新表定义
- supply_system_schema.sql: supplier_user_id→supplier_id(匹配实体) + 补充supply_commission
