Truncate counterparty address in tx list based on amount width

For every character beyond 10 in the amount string (e.g. "17.1900 USDT"
is 12 chars, 2 excess), remove that many characters from the middle of
the counterparty address, replaced with an ellipsis. Hover shows the
full address; clicking goes to tx detail which also shows it in full.
Prevents the address from wrapping onto a second line.
