Address some layout issues with odd content spacing on mobile, and footer position (#3022)

* - set vars for player container height and status bar height
- use them to calculate mobile top spacing to adjust for tab content positioning

* give main content section a min height, place footer absolutely at bottom; rm all the fixed footer styling

* cleanup; restructure tabbed display logic and css a bit

* Prettified Code!

* cleanup

* fix(story): footer story needs to be wrapped in RecoilRoot if it is to use Recoil

* revert adding footer to mobile about section

* prevent double scrolling
