Add localization for account holder auth and search detail pages

- Replace hardcoded Korean strings with translation keys in detail pages
- Add new translation keys for account holder services:
  - accountHolderAuth: title, detailTitle, requestDate, requestWay
  - accountHolderSearch: title, detailTitle
- Add 'result' key to common translations for reusability
- All labels now support Korean and English through i18n
