Apply t('home.count') localization to cash-receipt list page

- Replace NumericFormat with t('home.count') for transaction counts
  - approvalCount (승인 건수)
  - cancelCount (취소 건수)
- Remove NumericFormat import from cash-receipt list-page.tsx
- Remove duplicate count keys from locale files (keeping home.count)
