fix(android): removed kotlin-android-extensions plugin from build.gradle for compatibility with latest AGP and Kotlin

Summary

This pull request removes the deprecated kotlin-android-extensions plugin from android/build.gradle.

Motivation:

• The plugin has been deprecated and removed in recent versions of Kotlin and AGP.
• Its presence causes build failures in modern React Native projects targeting AGP 7.0+ and Kotlin 1.6+.

What the PR does:

• Removes apply plugin: 'kotlin-android-extensions'
• Adds apply plugin: 'kotlin-parcelize' to support @Parcelize if used
• Improves compatibility with modern Android build environments

Impact:

• Affects only Android build configuration
• No impact on JavaScript code or runtime behavior

Test Plan

What's required for testing (prerequisites)?

• React Native project using Kotlin >= 1.6.20 and AGP >= 7.0.0
• Forked and linked this updated package locally

What are the steps to reproduce (after prerequisites)?

1. Link this forked version of the package
2. Run npx react-native run-android
3. Verify that the app builds successfully
4. Confirm that upload functionality works as expected
