- CmsNavigationServiceImpl中增加model非空判断，防止model为null时报错
- 新增cms_model表中“案例(case)”模型数据，避免选择此模型时报错
- 保障后台栏目导航选择case模型时的保存操作正常执行
- 优化saveAsync方法，提升对未知模型的兼容性和稳定性

+-- 栏目模型「案例(case)」补充：解决后台栏目导航选择模型=case 时后端 NPE 报“操作失败”的问题。
+-- 后端 CmsNavigationServiceImpl.saveAsync 会按 navigation.getModel() 到 cms_model 查模型信息，
+-- 若不存在则 model 为 null，随后 model.getSuffix() 抛 NPE。
+-- 插入该模型后即可与 page/article/product 行为一致（banner/thumb/suffix 可被复用）。
+-- 说明：saveAsync 已改为 null 安全，即使本行未执行，case 也能正常保存（仅无 suffix）。
