Process phalanx moves from the front

When a selected phalanx contains more than one piece, this reverse loop moves the rear piece into the front piece's square and then the next iteration clears that same square, so ordinary multi-piece slides delete pieces. For example, red pieces at rows 5 and 4 moving north into an empty row 3 leave only the row-3 piece instead of preserving both pieces, which corrupts counts and win checks for both player and AI moves.
