[Cashtab] Improved styling for OrderBook

Summary:
Depends on D17051

Styling improvement for OrderBook components. Not to be treated as final.

Key changes

• If we have fewer than 4 offers, we render the tokenId on top of the depth bars
• Use all available horizontal space (wider depth bars)
• Use all available horizontal space for slider
• Add new noIcon param, which will render an OrderBook with depth bars only (for planned implementation on token landing page)

Test Plan:
npm test, check screenshots. Still available improvements but review this for "is this better than what we have"

OrderBook with 2 offers

OrderBook with 4+ offers

Orderbook with noIcon
