Rates persisted across a wallet connect and other user actions

[0xean]

When the swapper is exposed externally without a wallet connected and a user receives rates and then decides to connect a wallet, we want to ensure there isn't a full refresh required and they dont get kicked back into the flow.

Uniswap does a nice job of this ( https://app.uniswap.org/swap ) as an example.

AC

• swapper state persists upon wallet connection
• clicking back button from confirm screen returns to previous state vs full refresh
• moving from "mini swapper" on the markets page to the "full swapper" persists state

Spoke with @gomesalexandre and I'll focus on reviewing #8079 and wait until that goes in before starting this guy.
