<fix>[longjob]: clean stale progress on rerun

[zstack-robot-1]

When a failed LongJob is rerun, the old apiId's TaskProgressVO
records (containing 100%) were not cleaned up. The new execution
would inherit stale progress data, causing the UI to show 100%
immediately. Add deleteTaskProgress() for immediate hard-delete
and call it before updating apiId in the rerun path.

Resolves: ZSTAC-82077

Walkthrough

添加了新的deleteTaskProgress方法用于删除任务进度记录，并在长任务重新提交时调用该方法删除旧API ID的进度数据，防止显示过期的完成状态。
