Support the signed (uncapped) profile likelihood test statistic in the AsymptoticCalculator, like the ProfileLikelihoodTestStat already does with its SetSigned() option. When enabled and the best fit value of the POI is beyond the tested value, the sign of sqrt(qmu) is flipped instead of setting qmu to zero. The Gaussian asymptotic formulae remain valid in that case, so the p-values continue above 0.5 instead of saturating there. The qtilde corrections are skipped when the sign was flipped, because they apply when the best fit value is at the POI boundary, which is on the other side of the tested value. The option has no effect for the two-sided test statistics, whose asymptotic p-value formulae are symmetric in the sign. Closes [ROOT-8257](https://its.cern.ch/jira/browse/ROOT-8257). 🤖 Done with the help of AI
