Add <= 1e18 upper-bound check for all 8 input slots in the validation loops of both Optimizer.calculateParams() and OptimizerV3Push3Lib.calculateParams(). Previously only slot 0 (percentageStaked) had an overflow guard — slots 1-7 (averageTaxRate and future indicators) could silently accept values > 1e18, violating the documented [0, 1e18] invariant.
