Make the /calendar page look more like the google calendar

If you take a look at google's calendar (https://calendar.google.com), you can see that it takes up the full screen and has a navbar and sidebar for all the important functions. I think the calendar would be much easier to use, on both mobile and PC, if it could not be scrolled past and took up more of the screen just like google's version. This will require an entire redesign of the main-page-calendar component. Make sure that the changes only apply in the full mode, since this component is also used on the /home page!
