fix(errors): never let locale resolution break the error page

The withExceptions render hook called SetLocale::apply(), which resolves the
user via the DB — if the original error was a DB/user-provider failure, that
second access would throw inside the renderer and prevent the custom error page
from rendering (exactly when it's needed). Wrap it so any failure is swallowed
and the page renders in the default locale.
