chore: add custom FFmpeg AAR to repo for CI builds

feat: use custom FFmpeg AAR for Android, reduce APK size
- Replace ffmpeg_kit_flutter plugin with custom AAR (arm64 + arm7a only) - Add MethodChannel bridge for FFmpeg in MainActivity - Create separate pubspec_ios.yaml for iOS builds with ffmpeg_kit plugin - Update GitHub workflow to swap pubspec for iOS builds - Reduces Android APK size by ~50MB

+
+### Fixed
+- **Duration Display Bug**: Fixed duration showing incorrect values like "4135:53" instead of "4:14"
