Whole-branch review flagged that NewGame.construct validated class and
origin refs but not player.name. The canon-log schema requires
player.name with minLength:1, so a missing/blank name previously
returned ok:true and produced a log the API would reject with 422.

Also configure GUT to not treat push_error() as a test failure
(client/.gutconfig.json: failure_error_types = [engine, gut]).
The brief's LogPlayer/Quest setters intentionally push_error() on
rejected input; GUT's default failure_error_types includes
push_error, which would fail test_player_rejects_unknown_class and
test_quest_status_enum despite their assertions passing.
