fix: a saved wait in another shape reaches SuccessTx when its receipt arrives (closes #734)

A saved wait whose decoded record is in another shape threw when its
receipt arrived. WaitTx then stayed on screen with the counter stopped.
decodedDetailsHtml() now shows only the lines whose label and value are
text. SuccessTx shows the amount and recipient when no line can be read.

WaitTx and ErrorTx now show each allowance's Allowance token line. Long
amounts use break-words, so words stay whole. ErrorTx sets up copying
when it has no hash, so the token's address can be copied.

Model: opus-5-5
