Pull request overview

Refactors the self-consistency restart grid-version compatibility checks by delegating the HDF5/version validation logic (and associated exception type) to green-grids, reducing duplication inside green-sc.

Changes:

• Replaced sc_loop’s local grid-version consistency checker with green::grids::check_grids_version_in_hdf5(...).
• Moved/removed SC-local version compare utilities and the SC-local outdated_results_file_error, updating tests to expect the grids-level exception.

Reviewed changes

Just of for it, after considering the optional copilot changes (note that they would also have to be done in ac)
