Add comprehensive i18n localization to transaction UI components

- Localize 23 transaction UI component files
- Add 150+ translation keys to ko.json and en.json
- Organized translations under transaction namespace:
  * transaction.bottomSheet - Bottom sheet modals
  * transaction.sections - Section titles
  * transaction.fields - Field labels (90+ keys)
  * transaction.cancel - Cancellation flows
  * transaction.handWrittenIssuance - Manual issuance forms
  * transaction.list - List actions

Updated files:
- Bottom sheets: escrow-mail-resend, cash-receipt-purpose-update
- Sections: billing-info, part-cancel-info, detail-info, issue-info,
  escrow-info, important-info, payment-info, transaction-info,
  settlement-info, merchant-info, amount-info, cancel-bank-group,
  cancel-password-group
- Lists: list-item, billing-list, cash-receipt-list
- Cancel flows: all-cancel, part-cancel, prevent-bond
- Issuance: hand-written-issuance-step1, hand-written-issuance-step2
