Carb Time Stepper Respect Time limits

[gestrich]

There are limitations for how far you can deliver carbs in the past or future. It would be nice if the stepper would stop incrementing/decrementing when it reaches one of those limits.

I think I'll try this one.. capturing thoughts below:

• Compare now with carb entry limits and if exceeded disable the appropriate stepper
• The disabled state shouldn't react to an onTapGesture and should render gray
• Set the picker time to the entry limit on last tap before disabling
• If a stepper is disabled, show an error in the view about why it's disabled so users know how to correct

Open Questions:

• Should we also disable the date picker if a limit is exceeded?

I think going with Loop's UX choices is safe and I see they disable the date picker beyond its limits.

If you decide to do that, maybe look in LoopKit at the DatePickerRow which is used in Loop's CarbEntryView. You can at least see how they accomplish date limitations.

Ideally we could just reuse a UI component like DatePickerRow from LoopKit which Caregiver depends on. However there is sometimes special quirks to reusing the component in Caregiver requiring refactoring in LoopKit. So its a judgment call if worth trying to reuse it.
