Change profile target dynISF condition with HighTTRaisesSend

- Before this change, condition checked whether highTTRaisesSens was active AND user's profile target >= 118
- We received an issue report by a parent whose child runs with profile target set at >118, thus dynISF NEVER activated
- Change now moves this check condition to a saner target of halfBasalExerciseTarget, to ONLY disable dynISF if the user ACTUALLY sets a TT at a target value >= HBT (which by default is 160)
