fix: Resolve Dart type inference errors and update Android build configuration for Gradle 8.14

Type Annotation Fixes:
- fireNotificationList.dart: Added DeleteFireNotificationFunction and TapFireNotificationFunction types to _buildRow and _buildSavedFireNotifications parameters
- homePage.dart: Added Object type to catchError handler parameters
- redux/appReducer.dart: Added dynamic type annotation to action parameter
- redux/fetchDataMiddleware.dart: Added explicit type annotations and improved type casting
- redux/reducers.dart: Added dynamic type annotation to action parameter
- redux/userReducer.dart: Added dynamic type annotation to action parameter

Android Build Configuration Updates:
- Updated compileSdkVersion and targetSdkVersion from 34 to 36 to match plugin requirements
- Moved plugins {} block to first position (Gradle 8.14 requirement)
- Added dev.flutter.flutter-gradle-plugin to plugins block for modern Flutter integration
- Removed deprecated useProguard setting, replaced with shrinkResources
- Disabled Jetifier (android.enableJetifier=false) to improve build performance
- Increased JVM heap allocation to 4096M for large project compilation
- Added Kotlin language version 1.8 override for plugin compatibility
- Added ProGuard rules to exclude optional Google Play Core classes

Build Results:
- ✅ APK builds successfully (146MB debug APK)
- ✅ Zero type inference errors detected by dart analyze
- ✅ Kotlin compilation passes
- ✅ R8 minification configured correctly
- ✅ 301 remaining issues are all INFO-level style suggestions (non-blocking)
