Fix OpenMP warning and application restart loop

v1.3.9 - Fixed remaining deployment issues:
1. Moved OMP_NUM_THREADS environment variable BEFORE torch import
(was causing 'Invalid value for environment variable' warning)
2. Added reload=False to uvicorn.run() to prevent restart loop
3. Updated version to v1.3.9

Both outstanding issues from logs now resolved
