[Feature] /cronjobs page 1.x version can still be supported. Is it a separate import and export? Currently, manual jump version is a bit difficult to change the version manually.

### 1Panel Version

v1.10.30-lts

### Please describe your needs or suggestions for improvements

场景：
/cronjobs 下面有几十个任务，就想UI操作层面方便快捷，单独导入导出这个所任定时任务，不涉及整个1panel的备份..和其他复杂的操作

页面可以加入2个按钮，导入导出
