feat: Add theme-aware top-loading progress bar

This commit introduces a top-loading progress bar that provides visual feedback during page transitions, improving the user's navigation experience.

- **Package Integration:** The `nextjs-toploader` package has been added to provide a lightweight and efficient progress bar solution for Next.js.
- **Theme-Aware Color:** The progress bar's color is dynamically set using the `hsl(var(--sidebar-ring))` CSS variable, ensuring it automatically adapts to the application's current theme (light or dark mode).
- **Implementation:** The `NextTopLoader` component is integrated into the main `_app.tsx` file, making it active across the entire application.
