[Design]: Add missing hover states and transitions to the 404 Page buttons

[Aditya948351]

The Back to Home button on our custom 404 error page NotFoundView currently feels static. Please add a smooth CSS hover effect e.g. slight scale up, background color shift, or shadow to make it feel more interactive and consistent with the site.
