Configure Android app for Google Play Store production builds

- Add production keystore signing configuration to build.gradle
- Configure release builds to use production signing instead of debug
- Set up Android App Bundle (.aab) build type for Play Store
- Add FCM V1 service account configuration for push notifications
- Update gitignore to exclude keystores and service account keys
- Configure EAS for automated Play Store submissions

This enables production Android builds for Google Play Store deployment.
