[cleanup] Remove dead code do_update_all function

- Removed do_update_all function that was never called and only returned an error
- Removed "update-all" from OperationType enum as it's no longer used
- Regenerated data models to reflect the enum change

The update_all functionality now properly creates individual update tasks through the API endpoint rather than being a single monolithic task.
