Feat: Add partial success status to the app log

[Nov1c444]

Summary

Previously, there was no partial success status in the logs of workflow and chatflow. Now, workflow supports partial success. In chatflow, if all are successful, the status is success; if there is a partial success, the status is partial success; if there are failures, the number of failures is displayed.

Fixes #11458
