    Usable Items & Inventory Utilities Module
    -------------------------------------------
    This module provides functions for:
      • Registering items as usable across different inventory systems (ESX, QBcore, QBX).
      • Retrieving an item's image as a NUI link.
      • Adding and removing items from a player's inventory.
      • Toggling items in inventory (with server event for exploit protection).
      • Checking for item duplication exploits.
      • Handling tool durability mechanics.
      • Checking item availability and retrieving inventory.
      • Granting random rewards from a reward pool.
      • Checking if a player can carry specific items based on weight.
