Fix integer overflow. scaledBonus can reach rather large values, which lead to an int overflow as detected anematode using ubsan. (see https://github.com/official-stockfish/Stockfish/issues/6505#issuecomment-3696988889) It can be fixed by scaling nominator and denominator appropriately, which doesn't change the bench, as long as there is no overflow. First overflow/bench change happens at depth 26 closes https://github.com/official-stockfish/Stockfish/pull/6540 Bench: 2050811
