* Remove legacy export
* Extract view map to a switch case statement with typescript checking that all cases are handled
This lets us drop the `default` case as we know we will never reach it.
Additionally move all the settings conditions to the state-setters rather than the renderer so we are never stuck in an undefined state
* Fix comment
* Handle unknown screens better
Redirect to welcome/home rather than getting stuck at spinner
