/**
 * Coverage for POST /api/v1/logout, the bearer-authenticated
 * self-revoke endpoint added because Passport does not ship one (its
 * built-in DELETE /oauth/tokens/{id} is session-cookie authenticated
 * for the Passport-Vue self-service UI, and RFC 7009 revocation
 * expects client credentials rather than bearer auth). The endpoint
 * revokes the access token that authenticated THIS request and any
 * refresh token issued alongside it, but must leave the user's other
 * tokens (other devices, personal-access tokens, tokens under other
 * OAuth clients) untouched.
