Add i18n localization to support entity

- Add translation keys to support.qna namespace:
  - support.qna.registrationDate: QnA item registration date label
  - support.qna.status: QnA item status label

- Localize ui/qna-item.tsx:
  - Replace hardcoded "등록일" with translation key
  - Replace hardcoded "상태" with translation key

- Other support files (notice-item.tsx, faq-item.tsx) already localized
