Avoid consuming coal when refuel request fails

addFuelToMachine removes coal from the player before verifying that the full amount is available. If the player clicks “Refuel with 10 Coal” while holding only 3, those 3 units are taken from inventory, the call returns false, and the machine receives nothing. This silently burns scarce resources. Consider checking availability (or rolling back the withdrawal) before mutating inventory so a failed refuel leaves the player’s coal untouched.
