✅ Globally unique serial numbers — Previously, serial numbers reset with each batch (001-DDMMYY), meaning multiple QR codes across different batches could have the same serial. Serial numbers now use a unique database ID per QR code (e.g.,2619-100226), guaranteeing uniqueness across all batches.
✅ Serial numbers are now searchable — You can now search for QR codes by their serial number directly from the workspace. Previously, search only checked QR name, destination URL, and short code.
Existing QR codes retain their original serial numbers — the new format applies to all future bulk creations.
