Subject: [PATCH] Preserve influences on fetched trade items

Trader reconstructs fetched item text instead of decoding the supplied raw string. Restore historical and eldritch influence markers during that reconstruction so imported search results retain their influence.

Addresses the regression introduced by PR 10073.
