fix: Remove redundant signing steps from workflows

- Gradle now handles signing via build.gradle.kts with environment variables
- Removed ilharp/sign-android-release action (no longer needed)
- Removed manual zipalign step (Gradle does this automatically)
- Added verification step to ensure APK exists after build
- Fixes 'Output file exists' error in GitHub Actions
