 * cookie and then mint a persistent personal-access-token via the API
 * group, fully bypassing the second factor. ProfileController endpoints
 * now refuse when the session hasn't cleared 2FA, and the wrapper
 * IssueFreshApiTokenIfTwoFactorComplete refuses to issue the Passport
 * cookie in the same state.
