Improve About dialog version detection for different build types

🔧 Version Detection Improvements:
- Enhanced buildNumber detection to distinguish between local and GitHub Actions builds
- Local builds: CFBundleVersion is 7-char git hash (alphanumeric)
- GitHub Actions builds: CFBundleVersion is build number (numeric)
- Added logic to detect build type based on CFBundleVersion format

📱 About Dialog Enhancements:
- Version display now consistent across build types
- Build number shows appropriate value for each build type
- Git hash always shows first 7 characters for readability
- Better handling of different Info.plist formats

This ensures About dialog shows correct information for both local development builds and GitHub Actions releases.
