Feedback iPad: allocation grande + %, Home 2 columnas, YoY KPIs, achievements fix, iCloud calmado (build 58)

Allocation:
- Semicírculo responsive que llena su mitad de la fila (grande en iPad, no
  minúsculo en una esquina) + porcentaje dentro de cada segmento >=7%.
  SemicircleArc acepta center explícito; labels en el ángulo medio del arco.

Home iPad:
- Ya no columna única estrecha a 720. Hero + check-in a ancho completo, resto
  de cards en DOS columnas masonry independientes (sin acoplar alturas → sin
  gaps del grid). Cap 1100pt.

Year vs Year KPIs:
- Retorno del año actual + diferencia (pp) vs año anterior + mejor/peor año
  histórico. Usa forecastEndValue para el año en curso.

Fixes:
- 'View all achievements' en Journal no hacía nada: NavigationLink inline
  (frágil según contexto de navegación) → sheet fiable en cualquier sitio.
- iCloud: CKErrorPartialFailure tras una sync que funciona ya NO se pinta en
  rojo alarmante — nota calmada 'Sincronizando con iCloud' + detalle técnico
  en disclosure. Rojo solo si nunca ha sincronizado y es fallo total.
  syncErrorIsCritical + strings ×7.
