Create wrapper hook for react-toastify

[ivanng-oursky]

create a wrapper react hook around the react-toastify library to:

• ensure all content passed into toast are localized
• no duplicated toast from same error if called within useEffect

proposed API:

toast: {
  error: (messageID: MessageID, {locale config obj}, {toast option obj}): Promise<void>;
  info: (messageID: MessageID, {locale config obj}, {toast option obj}): Promise<void>;
  // and other toast types
}
