feat(epic-006): 完成故事006.002父子商品管理UI体验优化

## 变更内容
1. **移除未使用的导入和状态**:
   - 移除GoodsManagement.tsx中未使用的GoodsChildSelector导入
   - 移除未使用的batchCreateOpen和selectedParentGoods状态

2. **完善表单提交逻辑**:
   - 实现批量创建子商品mutation
   - 更新handleSubmit函数实际调用批量创建API
   - 修复父子商品数据同步

3. **设计完整的组件架构**:
   - 创建ChildGoodsList.tsx子商品列表组件
   - 创建BatchSpecCreatorInline.tsx内联批量创建组件
   - GoodsRelationshipTree.tsx已存在（复用）

4. **更新GoodsParentChildPanel使用新组件**:
   - 导入并使用BatchSpecCreatorInline组件
   - 导入并使用ChildGoodsList组件
   - 移除重复的批量创建逻辑函数
   - 优化UI交互体验

5. **编写完整的测试套件**:
   - 创建ChildGoodsList.test.tsx单元测试
   - 创建BatchSpecCreatorInline.test.tsx单元测试
   - 修复组件导入和错误处理问题

## 技术实现
- 父子商品管理面板支持创建/编辑双模式
- 批量创建组件支持模板保存和预定义模板
- 子商品列表组件支持分页和统计信息
- 保持与现有API的兼容性
- 遵循React Query最佳实践

## 待优化项
- 测试中的mock配置需要进一步优化
- 部分交互细节可以进一步优化用户体验
