fix: resolve nil method error in battlemart.lua callback

[omarcopires]

Description

I replaced the method npc:getFormattedCategoryNames(itemsTable) with the function GetFormattedShopCategoryNames(SupplyShopConfigTable), which correctly formats the shop category names.

This fixes the error and allows the NPC to properly display the selection of item categories.

Problem introduced in #2852
