Managed mode: list the phone OIDC card and drop the map model from the default settings pair

- MAdminOidcCard is markup over the settings section's state, so it is
  listed under mobileOnly with that reason.
- The default user settings views take their presets from
  useDefaultUserSettings now and import only a type from mapSettingsModel,
  so that pair names the map settings views alone.
