Resolve upstream merge conflicts while preserving OAuth extensions

Add explicit None checks for client_id fields before passing to functions
that expect str. This fixes type errors where str | None was being passed
to parameters that require str.

Changes:
- simple_auth_provider.py: Add client_id validation in exchange_client_credentials and exchange_token
- oauth2.py: Add client_id check at start of _apply_client_auth method
- test_auth_integration.py: Add assertions for client_id not being None in test mock methods

This ensures proper type safety and prevents potential None dereference errors.
