Explore checking the users nonce to safeguard against stale MM tx cache

[escottalexander]

Sometimes users have to start over and when they do they need to clear their MM wallet cache or else it thinks their nonce is higher than it should be. Their wallet will say that they have pending transactions right from the start. It is possible to get the users nonce with eth_getTransactionCount. If it doesn't line up with the transaction nonce we are about to request (this may be handled by the wallet as opposed to Wagmi in which case we will need to check their signed trasnaction for verification after handing it to them) then we show them a dialog with instructions on resetting the wallet cache and start them back from the beginning if necessary.
