fix: long symbols wrap on TxApproval and TransactionDetail, and SuccessTx keeps its amount and recipient (closes #743)

TxApproval and TransactionDetail cut off a long symbol, amount or description at
the edge of the screen. These lines now wrap.

SuccessTx hid its Amount and To lines whenever it had a decoded action, even one
that showed neither. Each line is now hidden only when a readable decoded line
shows the same thing. A swap with no Amount line now shows its amount on
SuccessTx, as WaitTx and ErrorTx do.
