feat(mat-product): 添加产品配料信息查询功能

- 在 IMatProductService 中新增 queryPageListWithMaterials 方法用于查询产品及关联配料信息
- 修改 MatProductController 的 list 接口返回 MatProductWithMaterialsVo 包含配料信息
- 在 MatProductServiceImpl 中实现产品配料关联查询逻辑和数据转换功能
- 新增 MatProductWithMaterialsVo 视图对象用于封装产品及配料信息
- 集成 matMaterialService 和 productMaterialRelationService 进行配料数据获取
- 实现 convertToProductWithMaterialsVo 方法将基础产品信息转换为带配料信息的 VO 对象
