Detailed Description

Round-trip regression test for the mechanical scalar configuration settings.

ReadConfig() and the settings-writing side used to carry independent, hand-synced config->Read()/config->Write() call pairs; if the two ever drifted (a typo, or a key renamed on only one side) the affected setting silently stopped round-tripping - the same recurring bug class the styles had before Configuration::StyleConfigKeys().

Both sides now iterate Configuration::ScalarConfigSettings(). This test guards that table: it perturbs every listed member away from its default, writes the settings to a temporary config file, reads them back into a fresh Configuration, and checks every member arrives unchanged. A future key or type mismatch leaves the fresh instance at the default value for that key and fails the test naming it.
