fix: a saved SuccessTx in another shape reopens as itself, and long amounts wrap (closes #740)

The popup refused a saved SuccessTx whose decoded record was in a shape it
did not expect, and showed Home. SuccessTx already shows only the lines it
can read, so the popup no longer checks the record first.

A long amount or token symbol was cut off at the edge of the screen. These
now wrap:

- the Amount figure
- each decoded amount
- the token symbol
- the name and description of SuccessTx's decoded action

WaitTx and ErrorTx share the line that shows the symbol, so they gain this
too.
