What this PR does / why we need it:

此次变更为文章分类引入了一个新的 preventParentPostCascadeQuery 布尔属性，用于控制分类及其子分类下的文章显示方式。具体变更包括：

• 在分类结构中增加了 preventParentPostCascadeQuery 属性。
• 当分类的 preventParentPostCascadeQuery 属性设置为 true 时，该分类的文章数量不会汇总到父分类中。
• 更新了树结构遍历逻辑，以支持对 preventParentPostCascadeQuery 属性的处理。
• 确保独立分类中的文章显示受控，不向上级分类进行聚合。
• 增加了相应的测试用例，以验证在不同树结构中 preventParentPostCascadeQuery 属性的功能性。

Fixes #3418

Hi @ruibaby 帮忙修改一下 UI： 分类列表需要为独立分类添加一个图标标识便于识别例如 link-break，文章列表需要修改分类查询的参数为 categoryWithChildren 且将分类的显示方式改为树状
