reviews: ask unico a premium existentes, funnel instrumentado y fix source unknown del paywall

- requestForExistingPremiumUser(): prompt nativo una sola vez para quien
  ya era premium antes del ask post-compra (evento review_prompt_premium_user)
- Funnel de semanas completadas emite review_funnel_shown/positive/negative/dismissed
- Paywall de Home via sheet(item:) con PaywallPresentation: el source viaja
  con la presentacion; antes dos @State separados hacian que a veces se
  registrara paywall_viewed con source=unknown (post_onboarding nunca llegaba)
