Charts 2.0 (build 49): sidebar nativa, filtros en toolbar, title menu en iPhone

El bug de Allocation/Contributions que no respondían en iPad persistía tras dos
fixes de lógica — la causa estaba en la capa de interacción (Buttons custom en
LazyVGrid dentro de ScrollView dentro de NavigationSplitView). Rediseño completo
alineado con el HIG:

- iPad: List(selection:) nativa con estilo .sidebar y secciones agrupadas
  (Overview/Analyze/Risk/Forecast) — hit-testing del sistema, navegación por
  teclado, pointer effects y VoiceOver gratis. El gating premium sigue en
  selectChart vía el binding de selección.
- Filtros (Group/Category/Sources) → Menu nativo en la toolbar con checkmarks
  e icono con badge cuando hay filtros activos. Desaparecen las pills apiladas.
- iPhone: toolbarTitleMenu — el título es el selector de chart (patrón
  Files/Freeform); fuera el carrusel de 14 chips. Periodo como segmented picker
  estilo Stocks encima de la gráfica.
- Slider de Performance integrado en el toolbar del chart (iPad) y como card
  compacta (iPhone).
- Eliminadas ~300 líneas de selectores custom (tiles, pills, chips).

Verificado con UITest nuevo (testChartSidebarSelection) en simulador iPad Pro:
tap en Allocation/Contributions/Rolling 12M carga cada chart, y el filtro de
periodo de Rolling reacciona. ScreenshotMode ahora activa debugPremiumOverride
para poder testear charts premium.
