fix: complete timeout float standardization

- Remove .total_seconds() calls in session_group.py (values are now floats)
- Update test_streamable_http.py to use float timeout values
- Change timeout=60 to timeout=60.0 in simple-auth-client example
- Change timeout=10 to timeout=10.0 in test_session_group.py
