Send: the recipient field grows to show it all; history steps aside while sending

- The recipient is a one-line textarea that wraps and grows (rows from
  the text's length over the field's measured width), so a whole address
  is in view in the field itself — no second copy in small type below.
  Enter doesn't break it and pasted line breaks are dropped. Empty, it is
  as tall as its hint (measured in the hint's own face), so that's whole
  too.
- Past the recipient — the amount, a review, a Lightning/Ark
  confirmation, a raw tx to broadcast — the history list below the send
  pane is left out.
- tools/send-dest-test.js (390px and 1280px).
