[bisq-network/bisq] Display up-to-date error messages under text fields (#5006)

[Jakub Loucký]

As user types into a validated text field,
if the new string is still invalid but the error message changed,
ensure the new message will be displayed.

Fixes #5005


### Before
Below are the states of a field as the value `0.0011` is being entered, and then cleared again.

### After
Now, the error message indicates the error condition every step of the way.
