Feature: Implement Material You (Material 3) Design

### Description

#### Description
I would like to suggest updating the UI of Ultimate Alarm Clock to use **Material You (Material 3)** design principles. Material You provides a more modern and personalized user experience, including:

- **Dynamic color theming** based on the system wallpaper
- **Enhanced dark mode support** with better contrast and readability
- **Updated UI components** that follow Google's latest design guidelines
- **Improved animations and interactions** for a smoother user experience

Implementing Material You could significantly enhance the app’s aesthetics and usability.

Would love to hear thoughts from the maintainers on this! Let me know if this is something you'd be interested in, and I’d be happy to contribute if needed.
