Bug in the export and import function of the Monitoring Center: some fields and data are lost
Steps to reproduce (HertzBeat v1.8.0):
When the scheduling type of a monitoring entry is set to a Cron expression, for example: 0/30 * * * * ?;
When there is corresponding data in the bound annotations.
Result:
Whether exporting all monitoring items or exporting specified ones, and regardless of whether the export file format is JSON or Excel, some fields and data are lost.

In addition, does the import monitoring function have complete field parsing? (Is it also missing parsing for fields such as the scheduler and annotations?)
