fix(test): translate the remaining Worn Shortsword and Padded Helm fixture names

Task 10 review sweep found two German strings the closing sweep missed:
'Abgenutztes Kurzschwert' (8 occurrences across 5 spec files, the real
seeded worn-short-sword item) and 'Gepolsterter Helm' (1 occurrence, a
synthetic test-only bonus-hp-helm fixture). Translated both to their
English equivalents per the item-content.ts glossary and slice style.
