Depricated API Warnings

When launching ComfyUI via `python3 ./main.py` ComfyUI manager (installed into .../ComfyUI/custom_nodes/comfyui-manager') will cause several deprivation warnings output into the log during server activation/runtime.

This is a fresh install of only ComfyUI (manual installation) and ComfyUI Manager.

```

Start by reproducing the warnings with `python3 ./main.py` using a fresh ComfyUI and ComfyUI-Manager installation. Inspect the listed legacy API paths, including `/scripts/ui.js`, `/extensions/core/groupNode.js`, and the button components, then verify that the startup log no longer reports deprecated API warnings.
