What happened?

When changing a workflow's interval from "manual" to "hourly" using the workflow editor UI, the change does not persist after saving. The interval reverts back to "manual" on next open.

Steps to reproduce

1. Create or have an existing Automation workflow set to "manual" interval
2. Open the workflow in the editor UI
3. Change the interval to "hourly"
4. Save the workflow
5. Re-open the workflow — interval is still "manual"

Expected behavior

The interval change should persist after saving.

Additional context

Workaround

Using the save_workflow tool programmatically with workflow_id and interval parameters works correctly.
