BioscopeBD iOS 2.33 / build 45 - native Google login update

THIS IS AN XCODE SOURCE PROJECT, NOT AN INSTALLABLE IPA.
Native iOS compilation and device login have not been verified on this Windows machine.
Requires a Mac/Xcode and Apple signing for a signed device build or TestFlight.

Build on Mac:
1. Extract, then run npm ci in ios/app.
2. Run npx cap copy ios (native Swift source already included).
3. Open ios/app/ios/App/App.xcodeproj and choose your signing team.
4. Build for your simulator/device. Test Google login, cancellation, sign-out, persistence and playback.
5. Archive and distribute using your own Apple signing credentials.

Included:
- Correct GoogleService-Info.plist for com.bioscopebd.app, plus its reversed client ID URL scheme.
- ASWebAuthenticationSession login with authorization code, S256 PKCE, random state and nonce.
- The official Google token is passed to Firebase Web Auth; Firebase validates it before creating a session.
- App-only native-auth.js intercepts the Google button, without weakening window.open or native popup rejection.
- iOS category scroll arrows hidden; touch swipe and genre/year filters preserved.
- Existing white app icon preserved.

The app loads the official website and same-origin player APIs. No website or Firebase settings were modified.
There is no generic external URL launcher or popup exemption. Google login uses only the fixed Google OAuth endpoint.
No account passwords, service-account keys, session tokens or test WebView profiles are included in this archive.
