Add diagnostic logging for network volume debugging

- Check if extra_model_paths.yaml exists at /comfyui/
- Print yaml content to logs
- Check if /runpod-volume is mounted
- List contents of /runpod-volume and /runpod-volume/models

This helps debug why models on network volumes might not be detected.
