fix: correct fee validation logic in market offer creation (#3250)

This fixes an issue with the market offer creation process where the player was incorrectly prevented from posting items for sale due to a faulty calculation of the required funds. The validation now ensures the player has enough money to pay only the market fee, rather than the total price of the items plus the fee.
