iPhone Duo (fase 1): navegación adaptativa por size class y layouts regular×regular

- ContentView: un único TabView (sidebarAdaptable en iOS 18+) para todas las
  size classes; desaparece el cambio de jerarquía iPhone/iPad, así abrir o
  cerrar el Duo conserva el estado de cada pestaña. @SceneStorage de la tab.
- Fuentes y Diario: NavigationSplitView (lista + detalle a la vez en ancho
  regular, stack colapsable en compacto) con selección nativa de List.
- Dashboard: Quick Update como .inspector (panel lateral junto a los gráficos
  en regular, sheet en compacto).
- Gráficos: chartHeightScale (+35% de alto en regular) vía chartFrame(height:),
  sin ignoresSafeArea en contenido interactivo.
- Liquid Glass (glassEffect) en las etiquetas flotantes del Diario en iOS 26+.
