- Replaced direct price calculations with a new method `normalizeDepthTargetPrice` to ensure valid target prices for buy and sell orders. - Updated all instances of price calculations in the MakerPointsEngine to utilize the new normalization method. - Added boundary tests for `getDepthBetweenPrices` to validate behavior when prices are exactly at the target.
