Subject: [PATCH] fix: refusing a From address the wallet does not hold moves
 nothing (closes #609)

Sign & Send wrote its refusal of a From address the selected wallet does not
hold onto the password error line, which reserves one line. The sentence runs
to about three, so it pushed Sign & Send down.

The refusal now has its own box above the password field, its sentence fixed
in index.html, holding its space from the first paint and only made visible,
as https://git.eeqj.de/sneak/AutistMask/issues/583 did for the other
refusals. Drawing the screen and each press hide it again. A Chrome test
writes the other wallet into the stored selection, reopens the popup onto the
screen, presses Sign & Send and checks that nothing was broadcast and nothing
moved.

Model: opus-5-5
