refactor: simplify node editor page and update admin page registry

- Removed the redirect logic from the NodeEditorPage, now directly rendering the DataFlowPage component.
- Updated the AdminPageRenderer to correctly register the new node editor page and adjust the cascading management imports for consistency.
- Enhanced the dynamic import logic to streamline page loading and improve performance.
