In function minimumMargin(), maximumLeverage being zero is not handled because it will result in div by zero as PRBMathUD60x18.div expects non-zero diTracer.
The impact is that various critical market functions will revert if maximumLeverage is zero. See issue page for effected code.
Recommend adding checks to make sure maximumLeverage is never zero or handle appropriately.
