♻️ refactor(goods-parent-child-panel): 优化组件代码和逻辑

- 移除未使用的图标导入（Trash2, X, Check, ChevronDown, ChevronRight）
- 移除未使用的状态变量 expandedParentId
- 移除未使用的查询选项 isLoadingChildren 和 refetchChildren
- 修复 API 端点路径，将 ':id'.setAsParent 改为 ':id'['set-as-parent']
- 优化 hasChildren 判断逻辑，处理 childrenData?.total 可能为 undefined 的情况
- 移除 onSaveTemplate 回调中未使用的 specs 参数
