Search, filter, and export workflow run details

Workflow logs and run details now make it easier to investigate large histories, repeated step output, and operational activity.

• Search inside workflow log steps and highlight matching output.

• Filter run history by activity while keeping selected filters visible.

• Export work done, errors, and warnings as CSV.

• See clearer request URLs, If/Else condition details, duplicate Run Workflow labels, and flow-control notification details in run history.
