Give the odd chip to the player the rule says gets it

Quick Split tells the dealer a leftover chip goes "to the first player left of
the button". The pot wizard, on the same tool, handed it to whoever the dealer
happened to tick first. Two screens, same split, different answer.

The wizard now orders the winners around the table from the button before the
calculator shares the pot out, so the leftover lands where the instruction says
it does. The calculator itself is unchanged — it already gave leftovers to the
front of the list, it was just being handed the list in the order the checkboxes
were clicked.

It's pennies, but it's pennies in front of the person who didn't get them, and a
dealer who has just read the other screen's instruction out loud looks wrong.
