feat: improve Vshare WebView with intent URL support and status bar padding

This commit addresses two UX issues in the Vshare WebView:

1. **Intent URL Support**: Fixed handling of intent:// URLs (e.g., Google Play Store links)
   - Added handleUrlLoading() method to intercept and process special URL schemes
   - Supports intent://, market://, and other app-specific schemes (mailto:, tel:, etc.)
   - Includes fallback mechanisms for better user experience
   - Displays appropriate error messages when apps are not available

2. **Status Bar Padding**: Added paddingTop to prevent content from being hidden
   - Added android:fitsSystemWindows="true" to WebView
   - Ensures content is properly displayed below the status bar in edge-to-edge mode

Changes made:
- VshareWebActivity.java: Added URL scheme handling logic with comprehensive fallback support
- activity_vshare_web.xml: Added fitsSystemWindows attribute to WebView
