test(mothership): mock Chip for the license-key guard tests on top of #8761

#8761 already guards the shown-once license key (generatedKey in isDirty, cleared on discard), so this branch keeps staging's settings page and its tests now assert that guard. The page now renders Chip, which the shared emcn mock does not provide.
