Refactor layout and home page for improved localization and session handling

- Updated RootLayout to include locale support and integrated ThemeProvider and LocaleProvider for better internationalization.
- Replaced static home page content with a redirect based on user session status, enhancing user experience by directing to the appropriate dashboard or login page.
- Switched font from Geist to Inter for improved typography consistency.
