Revert to working OMP_NUM_THREADS approach from SHA 9201e6d

v1.4.6 - REVERT to working configuration:
- You confirmed SHA 9201e6d fixed OMP_NUM_THREADS issue cleanly
- That used: Python os.environ override + simple CMD ['python', 'app.py']
- I kept changing Dockerfile CMD after it worked, causing regression
- Reverting to proven working approach instead of complex shell commands

Back to basics that worked!
