Growth y monetización: fixes críticos, paywall multi-plan, teasers y App Intents

CRÍTICO — enlaces del App Store rotos (adquisición viral = 0):
- GoalShareService.appStoreURL apuntaba a id6744983373 (404): el QR de TODAS las
  imágenes compartidas llevaba a una página muerta. Corregido a id6757678318.
- SettingsView enlazaba id6741412965 (una novela romántica). Ahora usa la constante.

Monetización:
- IAPService multi-producto: sub anual (com.portfoliojournal.premium.annual, con
  intro offer/trial) + lifetime como ancla. isPremium acepta cualquiera de los dos.
  Paywall con selector de plan (anual por defecto si existe; degrada a solo lifetime
  mientras el producto no esté creado en App Store Connect).
- paywallBenefits: añadidos Multiple Accounts y Family Sharing (diferenciadores).
- Teaser de historia bloqueada en Charts: "N meses más con Premium" en vez de
  truncar en silencio (FreemiumValidator.hiddenHistoryMonths + banner).
- Trigger de paywall de backups ahora instrumentado (logPaywallShown "backups").

Retención / adquisición:
- Rating velocity: prompt tras 2 check-ins y 30 días (antes 3 + 90 — en una app
  mensual eso era >3 meses sin poder pedir la primera review con ~0 ratings).
- Sample data ON por defecto en onboarding (skip ya no aterriza en dashboard vacío).
- Notificación de protección de streak el día 25 si el check-in del mes está pendiente.
- App Intents + AppShortcutsProvider: "Update my portfolio" / "Check my portfolio"
  vía Siri/Shortcuts/Spotlight.
- Instrumentación: onboarding_step/onboarding_skipped y content_shared (viral loop).
- ScreenshotMode (--screenshots) para capturas de marketing automatizadas.

ASO:
- 6 locales nuevos en metadata (en-GB, en-CA, en-AU, es-MX, fr-CA, pt-PT) reusando
  traducciones — 6 campos de keywords extra; pt-PT adaptado (reforma).
- Categoría secundaria: PRODUCTIVITY.
- 17 strings nuevas localizadas en los 7 idiomas.

Pendiente manual: crear la sub anual en App Store Connect (grupo de suscripción +
intro offer 7 días) con el id exacto com.portfoliojournal.premium.annual.
