What this PR does / why we need it:
- replace footer actions with confirm for sub forms in edit-template
编辑模板中，进入子表单时，Footer 上的保存按钮难以发现，并带有歧义，调整子表单的保存方式为确认框
- add loading status to detail layout to prevent permission judgment errors
详情页模板添加加载中状态，避免 UI 在基础数据获取完成前渲染，导致详情页操作可能展示不出来
- resize the loading icon
优化加载中图标显示，更改图标大小为默认 medium
