i18n: one label_or_name for lists mixing labels and names; normal style rows

panels::label_or_name and dialogs::shown_names applied the same rule; it
now lives once as i18n::label_or_name (explicit language, testable) and
both delegate to it. zh-hant gains the two normal text style names the
Character and Paragraph Styles panels translate.
