Fix Google Play rejection issue in React + Vite + Capacitor Android app

I need help fixing a specific issue in an existing Android app.

The project is already built. It was originally created with Lovable AI, but it is now exported as a normal React + Vite project using Capacitor for Android.

Backend/auth is Supabase.

The app was rejected by Google Play because it still seems to redirect or reference Lovable. I need someone to review the exported source code and Android/Capacitor configuration, remove/fix any Lovable references or redirects, and make sure the app works correctly with Supabase and Google Play.

This is not a full app development project. The app already exists.

Required experience:
- React + Vite
- Capacitor Android
- Supabase Auth
- Android build process
- Google Play Console / app rejection fixes

What I need:
1. Review the project.
2. Identify the exact cause of the Lovable redirect/reference issue.
3. Fix the issue in the source code/configuration.
4. Make sure the project is ready to build as an Android AAB.
5. Provide a short summary of the files/settings changed.
6. Provide clear build instructions.

Important security note:
I will NOT share the keystore, signing passwords, private keys, Supabase service_role key, or Google account credentials.

I will generate and upload the signed AAB myself.

I can provide:
- Source code ZIP
- Google Play rejection screenshots/message
- Supabase public URL and anon key if needed
- Screenshots of Supabase settings if needed

Please apply only if you can work with the exported React + Vite + Capacitor project and fix this specific issue.
