docs(py): sync docstrings with code in tools.restart2solution and run.projection

- tools.py: update restart2solution docstring to match signature (state=None), per review.
- projection.py: clarify that the 'state' parameter is accepted for API compatibility and currently unused.
- No functional changes.
