Amount of orders on orderbooks page

[tonymorony]

I think it might be quite helpful for user to have on this screen total amount of orders for given pair

Since there might be many possible pairs options in DEX and since we're on stage where there is not many orders user might need to click a lot of options to find the pair with >0 amount of orders. To not break overloads we might just highlight VRSC and user will learn what that means

Option with numbers - overloads UI a little bit:

Option with highlighting (it might be highlighting by font colour change also) of alive pairs - overloads UI less imo:
