fix: the connection prompt shows the shared address whole (closes #517)

The element holding the address on the connection prompt was a flex row,
so the title line and the address that renderAddressHtml() returns sat
side by side and the address got only the width left over, which hid its
last nine characters. It is now a plain block, as on the signature
screen, so the address has a row of its own. The Chrome browser suite's
connection test now measures that row with the check the other screens
already use.
