Add i18n support for empty state when no barcode data is found:
**English translations:**
- "No Barcode Data Found"
- "No bills with 2D barcodes found for {yearMonth}"
**Croatian translations:**
- "Nema Podataka o Barkodovima"
- "Nema računa s 2D barkodovima za {yearMonth}"
**Implementation:**
- Add translation keys to messages/en.json and messages/hr.json
- Update server component to fetch empty state translations
- Use proper next-intl parameter passing for yearMonth variable
- Replace hardcoded English text with localized translations
Empty state now displays correct language based on URL locale:
- /en/print/2025/01 → English empty state message
- /hr/print/2025/01 → Croatian empty state message
