chore: adjust glucose limits

Match 'normal' glucose range of 80-120

This is not a medical recommendation but a mere UI choice: 99 is just the maximum 2-digit number that doesn’t make the labels move :-)

SwiftUI doesn’t let you customize easily like in UIKit the colors of both the left and the right segments of a slider since there is no SliderStyle: a more ideal solution would be to use a single slider with four thumbs, the center target range colored in green and red alarms thresholds at the margins but without wrapping an UISlider in a UIViewRepresentable.

I am optimizing the SettingsView to be controlled comfortably at the thumb’s reach, without needing to scroll it: in smaller displays thumbs cannot be accurate so I am leaving some leeway purposely.

Ok for 99, but why start at 140 lowest then (my alarms are set at 75/130 :) )

OK. 239cd0a lowers to 120 the targetHigh / alarmHigh sliders low ends.

Since our Vendor is targeting also athletes with the Biosensors and supporting all those “metabolic health” startups (I was contacted already by a dozen of them), let’s support them, too ;-)

Works for me !
