The Login button in the navigation bar was previously a static UI element. This commit converts it into a functional Next.js `<Link>` component.
The link now directs users to `https://app.opplens.com` and opens in a new tab (`target="_blank"`) to provide access to the application's login page. Additionally, a vertical margin has been added to the navigation bar for better spacing.
