Redesign the workflow editor experience

Related to novuhq#6750

Redesign the workflow editor interface based on learnings and introduce advanced data manipulation features.

* **WorkflowEditorProvider**: Add new helper components `For` and `Liquid` for advanced data manipulation. Update `addStep` function and `WorkflowEditorContext` to include these components.
* **WorkflowEditor**: Update the `WorkflowEditor` component to support a hybrid code/no-code environment. Add new tabs for advanced data manipulation.
* **WorkflowList**: Update the `WorkflowList` component to reflect the redesigned interface. Add new columns for advanced data manipulation.
* **EditWorkflowPage**: Update the `EditWorkflowPage` to use the redesigned workflow editor components. Modify `asideClassName` to include new styles for advanced data manipulation.
