feat: implement mass balance validation for Story 7.1

- Added port_mass_flows to Component trait and implements for core components. - Added System::check_mass_balance and integrated it into the solver. - Restored connect methods for ExpansionValve, Compressor, and Pipe to fix integration tests. - Updated Python and C bindings for validation errors. - Updated sprint status and story documentation.
