Input rows switch to a two-line layout (full prev-txid:index on the first
line, address + amount on the second) so nothing is cut by a fixed 160px
column. Output address column gets TextWrapping instead of TextTrimming.
Overlay grows to MaxWidth=660/MaxHeight=800 for better desktop use; the
same XAML wraps naturally on narrow mobile screens.
Removes the Shorten() helper that was masking input references.
