Subject: [PATCH 4/5] chore(libraries): update IAPKit URL references to
 kit.openiap.dev

Update comments, env examples, and plugin JSDoc across
expo-iap, react-native-iap, flutter_inapp_purchase, and kmp-iap
so all "Get your API key from" pointers target kit.openiap.dev.

Subject: [PATCH 5/5] docs: address PR #102 review feedback

- Navigation: mirror IAPKit link in mobile menu (gemini-code-assist)
- navigation.css: switch CTA text to #000000 for WCAG AA contrast
  over gradient (coderabbitai)
- purchase.tsx IAPKit section:
  - Soften "no server code required" to clarify that
    accounts/entitlements should still be granted from a trusted
    backend (coderabbitai)
  - Swift: rename type to RequestVerifyPurchaseWithIapkitAppleProps
    and use the "IAPKitAPIKey" Info.plist key that matches the
    Expo plugin output (gemini-code-assist)
  - Kotlin/KMP/Dart/GDScript: rename Apple/Google props types to
    ...AppleProps / ...GoogleProps to match
    types/verification.tsx (gemini-code-assist)
