fix: update onnxruntime dependency to >=1.22.1 for Windows Server 2019 compatibility

- Update onnxruntime constraint from ==1.22.0 to >=1.22.1 in pyproject.toml
- Add test to verify onnxruntime version constraint in test_imports.py
- Add comprehensive tests for ONNX embedding functionality
- Fixes issue #3398 where onnxruntime 1.22.0 causes DLL load failures on Windows Server 2019

Resolves: #3398
