重构包装管理服务，优化数据结构与接口

移除 APIPackagingManageService，功能迁移至 HJGLPackagingmanageService 并进行重构，新增方法支持包装与组件关联管理、分页查询、状态描述等功能。
更新 PackagingManageController，替换旧服务调用，新增接口方法。
调整数据库结构，新增子表 HJGL_PackagingManageDetail，优化包装与组件的关联存储。
更新前端页面逻辑，适配新数据结构，新增 StackingPosition 字段显示。
优化 Model 层字段定义，调整长度限制，提升性能与一致性。
更新报表模板与项目文件，移除冗余代码，提升代码可维护性。
