more realistic loading state into WardrobePage

Here, we extract a lean WardrobePageLayout component, so that we can bundle it into the main app as a loading state for WardrobePage.

This means that clicking Start from the homepage will, instead of flashing the screen to white while WardrobePage loads, show the correctly-sized black/white page layout instead.
