Minor website lookout update

We did a minor website layout design update.
Finally, I spent some time on the page code, and from now on, each link in the menu is on a separate line.
Additionally, the menu links are no longer written in capital letters, making it undoubtedly look more aesthetically pleasing than before.
Also, the subpage with the history of the website was edited and returned to readability. For a long time, there was only information that it was temporarily (Yes, 2 years is really just a moment) unavailable.
