Fix GPU compatibility: use standard onnxruntime (auto-detects GPU at runtime)

- Removed onnxruntime-gpu which requires CUDA libraries in base image
- Use standard onnxruntime package which auto-detects GPU if available
- Build will succeed, GPU will be used automatically at runtime if CUDA is available
- API code already handles GPU/CPU fallback properly
