Add multi-select to the inventory and a "Print labels" flow that renders a PDF sheet of labels (small stickers or large cards), each carrying the seed's common name, variety, scientific name, year/origin and a tanemaki://seed QR that holds the seed's data offline (future scan-to-import). - SeedLabelCodec: compact, versioned tanemaki://seed URI (encode/decode) - LabelSheetService: pure-Dart PDF grid (pdf + barcode + DejaVu), RTL-aware - VarietyRepository.labelRows: one row per lot, locale-picked common name - InventoryCubit selection mode; contextual app bar + label print sheet - i18n en/es/pt (printLabels.*) Tests: codec, PDF service (both formats + RTL), labelRows, selection cubit, inventory widget selection.
