refactor: Simplify VshareWebActivity by reusing app theme system

- Use NoneSlideBackableTheme instead of GalleryTheme for proper theme inheritance
- Remove manual SystemUI configuration code (now handled by theme)
- Add proper edge-to-edge display with LAYOUT_FULLSCREEN and LAYOUT_HIDE_NAVIGATION flags
- Fix layout background to use transparent color compatible with NoneSlideBackableTheme
- Set status bar icon color dynamically based on dark/light theme

Benefits:
- Reduces code duplication by leveraging existing theme infrastructure
- Automatic theme switching support (follows app's day/night mode)
- Consistent UI behavior with MainActivity
- Simpler and more maintainable code
