Fixed overflow and dragging problems

[NoobCrewDelux]

Added a mutation observer in the session wrapper to apply { draggable: false } to all "img" and "a" tags via the querySelectorAll function.

I used this because if we were to use global styling we would need to disable pointer-events on the "img" and "a" tag. This breaks things massively ( specifically if we do it on the "a" tag). So I decided to avoid using css entirely, and just apply the draggable attribute to each "img" and "a" tag. This prevents issues further down the line with debugging styling.

We would need to disable pointer events on the "a" tag because next/Link uses "a" in the DOM.

Put overflow-hidden in the root layout to clip everything to the viewport. This works everywhere unless you explicitly change the overflow behavior further down the DOM.
