fix: update QR code print layout to show payedAmount instead of yearMonth

Remove billYear and billMonth from second column, add payedAmount as last value.
- Update PrintBarcodeData interface to replace yearMonth with payedAmount
- Modify fetchBarcodeDataForPrint to include bill.payedAmount
- Update PrintPreview display to show payedAmount (formatted from cents)
