Fix module import path for Hugging Face Space

Changes:
- Add try-except for import path resolution
- Try 'backend.process.image_process' first (HF Space structure)
- Fall back to 'process.image_process' (local deployment)
- Ensures compatibility with both environments

Fixes: No module named 'process' error on HF Space
