Refactor theme management and enhance UI components for improved user experience

- Removed the `animejs` dependency and replaced it with a lightweight animation system using the Web Animations API for better performance.
- Introduced theme settings in `SettingsModal.vue`, allowing users to select between light, dark, and system themes.
- Updated `useUIStore` to manage theme state and apply changes dynamically, enhancing the overall UI consistency.
- Improved styling in `VndbPanel.vue` and other components to align with the new theme management system, ensuring a cohesive look and feel across the application.
