- settlement.settlementCompleted, depositScheduled
- settlement.settlementInfo, transferStatus, transferId, transferTime
- settlement.bankName, accountNumber, depositorName
- settlement.settlementDepositAmount, errorReason
- settlement.transactionDetailInfo
- settlement.cardBankTelecom, approvalAccountPhone
- common.weekdays.* (sun-sat)

Localized components:
- filter/list-filter.tsx

- info-wrap/settlement-info-wrap.tsx
- info-wrap/transaction-info-wrap.tsx
