feat(auth): 树勾选级联+点击文字勾选+树默认闭合

- 新增共享级联工具 utils/treeCascade.ts：勾选子->祖先全部勾选；勾选父->子孙全部勾选/取消；取消子->父/祖不受影响（zTree 侧 chkboxType 置空，由代码级联）
- GroupAuth.vue：接入代码级联，模块明细按 diff 提交（追加/删除），取消时同步清理子组继承标记
- AppModuleCheckTree.vue：角色授权接入同一套级联逻辑
- 组/角色授权树与应用节点默认闭合，点击文字等价勾选框（MyTree onClick 同步触发 onCheck）
- PermissionView.vue「已授权应用」应用一级默认不展开模块
