fix: the wait and error screens show a swap's Moved from the sender amounts (closes #722)

A swap's Amount figure can leave out what its Moved from the sender lines take, so these screens could read as if less left the wallet than can have left. Both now show each of those amounts under the figure, using the decoded details they already receive. The error screen saves those details too, so a reopened popup keeps the lines. A saved record in another shape shows only the lines it can read. Model: opus-5-5
