Add flavor-specific app icons setup for Android and iOS

- Create documentation for configuring flavor-specific app icons in mobile applications.
- Implement scripts to generate and set up flavor-specific icons for Android and iOS.
- Configure iOS schemes to use the appropriate AppIcon asset sets for dev and stage flavors.
- Ensure generated icons meet required sizes and formats for both platforms.
- Provide troubleshooting steps and CI/CD integration guidelines for automated builds.
