Token refresh

Since MOVE SDK v2.6.7, token refresh is handled automatically and internally by the SDK. Host applications using setup(...) do not need to implement any token refresh logic.

The SDK uses the refreshToken internally to obtain a new accessToken whenever needed, without any action required from the host app.

Authentication State Monitoring

The host app should monitor MoveAuthState via the AuthStateUpdateListener. The only actionable state is INVALID. When this occurs, the user should be logged out and shutdown(force: true) should be called.
