Basemap Style Cleanup

We noticed that the current implementation includes some outdated basemap styles and lacks clarity on platform-specific support. To improve usability and maintainability, we propose the following enhancements:

- Remove old or deprecated basemap styles from the codebase.
- Document platform-specific styles with inline comments (e.g., if a style is only supported on web or mobile).
- Enhance the example app to include a dropdown menu for switching between all available basemap styles. This UI can be placed on a separate page to keep the main example clean.
