fix: keep other plugins' slot display for food on their furniture (#59)

PlateManager.addItem had a stray semicolon after its furniture check, so
every food item placed on any InteractibleFurniture slot got the cooking
display pose (flat, full size). Salt on magic pedestals showed oversized.
Only apply cooking display data to Cooking-owned furniture.
