feat(build): add automated Android resource detection and generation

- Add generate-android-icons.sh script to create all required launcher icon sizes - Add check-android-resources.sh script to detect and fix missing Android resources - Integrate resource check into build-android.sh to prevent build failures - Fix splash screen resource naming (splash-dark.png -> splash_dark.png) - Add SplashScreen plugin configuration to capacitor.config.json - Automatically generate missing mipmap icons from assets/icon.png - Fix XML resource references to use correct drawable paths Author: Matthew Raymer SECURITY AUDIT CHECKLIST: - [x] No sensitive data exposed in generated resources - [x] Resource generation uses safe file operations - [x] Scripts include proper error handling and validation - [x] All generated files use appropriate permissions - [x] No hardcoded secrets or credentials in scripts
