How to add new auth panel

To add new panel you need to:

create panel component at components/auth/[panelId]
add new context in components/auth/PanelTransition
connect component to router in pages/auth/AuthPage
add new state to services/authFlow and coresponding test to tests/services/authFlow
connect state to authFlow. Update services/authFlow/AuthFlow.test and services/authFlow/AuthFlow.functional.test (the last one for some complex flow)
add new actions to components/auth/actions and api endpoints to services/api
whatever else you need
