chore: Dynamically import email functions in authentication routes to optimize build process

This commit modifies the authentication routes to dynamically import email functions, preventing Resend initialization during the build. This change enhances the application's performance and reliability by ensuring that unnecessary initializations do not occur at build time. These updates contribute to a more efficient development workflow and improve the overall user experience.
