Current subscription status and renewal date visible in app

A paying subscriber who cannot see their renewal date, current tier, or next charge amount inside the app has to dig through App Store or Play Store settings to answer basic billing questions — and many will just email support or dispute the charge instead. Hiding subscription status is also a common trigger for App Store Review Guideline 3.1.2 rejections on subscription transparency. The data is already in customerInfo.entitlements.active[...] on every launch; not surfacing it is pure UX negligence.

Add a subscription status block to the Settings or Account screen that reads from the IAP SDK's cached customer info and renders tier, renewal date, and next billing amount. In src/screens/SettingsScreen.tsx:

const customerInfo = await Purchases.getCustomerInfo();
const premium = customerInfo.entitlements.active['premium'];
if (premium) {
  return <Text>Premium — renews {premium.expirationDate}</Text>;
}

Include trial end date when a trial is active, and link to the platform's native subscription management screen for cancel/change flows.
