feat: Main node shows "New" and drops "Show" from toggle labels

Shorten a few Main-node param display labels without touching their
`name` (the dispatch identity used by execute_menu_action and the live
toggle refresh): "New Project" -> "New", and every "Show ..." toggle
loses its "Show " prefix. The params pane keys off `label` when set, so
sync_parameters_to_project now resolves a click back to its param by
that display key rather than by name alone.
