feat(ui): render the active style in the dock and the ACTIVE STYLE corner from the store

VisualSettings no longer toggles the style buttons' active class or writes
the dock's style mini status and the ACTIVE STYLE corner. It publishes the
active style and its label to the gev-display store; CommandDockView and
SceneChromeView render them. The buttons keep their owner's listeners, and
the initial label renders through t().
