fix(notifications): zh-CN for the display-time settings, and review leftovers (#564)

- zh-CN entries for the two new rows (label and description).
- The toast test header still described the dropped drawer logging, and the
  noise test typed three members nothing uses any more.
- clickNotification's closing brace had been re-indented by accident.
