Make error message layout consistent #560

Currently, the error message for invalid change address is displayed on the right while in the "Pay to" and "Address" fields do not show the error message, as commented in #553 (comment).

This PR makes the address error feedback consistent across all fields.

Supersede #534

I assume in this figure there is a static placeholder for the red label (normally empty):

I assume that's regular P2WPKH invoice address you are showing.

Would mean the destination address box be shorter. So what happens if destination address is a longer P2WSH address? Would it then clip while with the current code it would not?

tACK commit 9d75184fe7d915e05ac01d50cec90881594ef19a

Tested all address types in the 'Pay To', 'Custom Change Address', and 'New Send Address' fields.

Just noting that it says "Warning: Invalid Bitcoin address" immediately, but only highlights red when you click out of the text box. I don't know if I have a preference there. But I like the change.

I get this message when opening:

QVariant::load: unknown user type with name BitcoinUnits::Unit.
