Properly show balance and tokens

[fkrause98]

🐛 Bug Report for zkSync CLI

📝 Description

When doing either a withdraw, deposit or finalize withdraw, you get a message like this:
Sender L1 balance after transaction: 99999999999991999999.81035896797446877 lambdacoin.
Which can be a little misleading, since it is actually showing the wallet's ETH balance.
We should decide if we either want to show:

1. The ETH balance (which makes sense since you have to a pay fee for the withdraw).
2. The ERC-20 balance, since these three operations would involve a non-ETH token.
3. Both.
