✨ feat: Implement theme switcher in header

Browse Source 
This commit introduces a theme switcher component in the header, allowing users to toggle between light and dark modes. The changes include:

- Added a new `ThemeSwitcher` component in `components/header/theme-switcher.tsx` that handles the theme switching logic and UI.
- Integrated the `ThemeSwitcher` component into the `HeaderToolbar` component.
- Updated the global CSS file (`app/globals.css`) to include styles for the light mode.
- Initialized the theme based on user's previous preference or system preference.
- Saved the user's theme preference in the browser's local storage for persistence.

These changes provide a better user experience by allowing users to switch between light and dark modes, which can improve readability and accessibility, especially in different lighting conditions.
