Fix interaction context and adventure character name translation

- Interaction messages now show which item triggered them (e.g., "You use
  Golden Key — the key fits!") instead of appearing without context.
- Adventure character names are resolved from their Loreline script name
  field before localization lookup, fixing IDs like "knight" showing
  instead of translated names like "Sire Boîtalot".
