Each label in the print sheet gets an editable copy count, suggested from
the lot's latest condition-check container count (3 jars → 3 labels), and
falling back to 1. Type or step the count; the total updates live and Save
is disabled at zero. On save each seed expands into that many identical
labels.
- SeedLabelEntry.suggestedCopies; labelRows reads the latest container count
- label print sheet: per-row −/number/+ stepper, live total, expand on save
- tests: repository suggestedCopies + print-sheet copy chooser
