i18n: syntax-check translations at runtime

We often call str.format() on translated strings.
E.g. `_("time left: {} seconds").format(t1)`
If the translated string has a different format syntax, this can raise at runtime.

This PR adds some runtime checks that try to ensure the source string and the translated string
have a similar format syntax. If the checks fail, `_()` will "reject" the translation by
returning the source string.
