feat(product): 新增产品管理功能模块

- 新增产品管理控制器ProductController，提供创建、更新、删除、详情、分页查询等接口
- 新增产品服务接口ProductServiceI及实现类ProductServiceImpl，用于业务逻辑处理
- 新增产品相关命令和查询对象，如ProductCreateCmd、ProductUpdateCmd、ProductPageQry等
- 新增产品实体类Product及其数据传输对象ProductVO和ProductDO
- 新增产品网关接口ProductGateway及实现类ProductGatewayImpl，封装数据访问逻辑
- 新增产品转换器ProductConvert，支持DO与Entity之间的映射
- 新增产品Mapper接口ProductMapper，继承BaseMapper并扩展批量重置排序方法
- 完成产品模块从控制层到数据访问层的完整链路开发与集成
- 支持产品拖拽排序功能，包括前后位置计算与间隙不足时的重新排序逻辑
