fix(i18n): keep activateReason default untranslated per review

Commonlib compares this value against the raw "updated" literal to
distinguish automatic activation from a user-requested run, so
translating it changes behaviour rather than just the displayed text.
Keep the default raw and drop the "updated" catalogue entry; the
manually-requested reason stays translated.
