Improve ETH workflow confirm message

[anxolin]

This issue, although is not a critical, it feels like low effort, and improves a little the ETH workflow.

The idea is that, instead of showing the balances, it would be nice to see the resulting balances AFTER I perform the Wrapping.

Also, if ETH balance is low, maybe it should even be red, like in this case:

Something like:

1.8 ETH                           ---->          1.8 WETH
balance after: 0.1 ETH                    balance after: 3.5 WETH (edited) 

(ofcourse in the example, i removed decimals to simplify the example, but it should have decimals)
