Fix React serialization warning when passing ObjectIds to client components:
**Problem:**
- MongoDB ObjectIds have toJSON() methods which React rejects in client components
- Error: "Only plain objects can be passed to Client Components from Server Components. Objects with toJSON methods are not supported"
- Occurred when rendering main page with year parameter (?year=2023)
**Solution:**
- Add $addFields stage in fetchAllLocations aggregation pipeline
- Convert location _id and bill _id fields to strings using $toString
- Simplify $project stage to use single "bills": 1 instead of individual field projections
- Ensures only plain objects (strings) are passed to client components
**Technical Details:**
- Modified app/lib/actions/locationActions.ts:268-287
- Added $addFields stage before existing $project stage
- Converted ObjectIds to strings while preserving all other data structures
- Build passes without serialization warnings
ObjectId serialization now handled properly across all client component boundaries.

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

Fix IntlError: FORMATTING_ERROR for print footer translation:
- Pass date parameter correctly to t("print-footer") in server component
- Remove manual string replacement in client component
- Use proper next-intl parameter syntax: t("key", { param: value })
Error was caused by next-intl expecting translation parameters
to be passed at the translation function call level, not through
manual string replacement afterward.
Print preview now loads without FORMATTING_ERROR and displays
localized footer text correctly in both English and Croatian.
