ui: define (write|status|warn|note)noi18n aliases

We currently use `write(('...'))` to suppress check-code warnings
about not using translated strings. However, when we run black, it
will strip the `((...))`. In order to placate black, we'll need to use
a different mechanism to pass untranslatable strings. This commit
introduces a `writenoi18n` alias (and friends) to `write` for that
purpose.
