feat: update app icon with single high-resolution asset

Modernize app icon configuration to use a single high-resolution
image (1024x1024) that Xcode automatically scales to all required sizes.

Changes:
- Replace multiple icon size variants with single v1.png asset
- Update Contents.json to use single-size configuration
- Remove deprecated demo and logo image assets
- Simplify icon management for future updates

Benefits:
- Reduces asset maintenance overhead
- Uses modern Xcode app icon best practices
- Smaller repository size by removing redundant sizes
