Quick bolus: redesign sheet with pills, slide-to-enact, and settings toggle

- Replace List-based picker with 3 capsule pills in an HStack; tap to select
- Replace confirmation dialog + biometric with a slide-to-enact control
  (SlideToConfirmView) that triggers Face ID/Touch ID on completion
- Add QuickBolusInfoView with "Got it!" button replacing toolbar Done
- Add QuickBolusConfig settings module with enableQuickBolus toggle,
  wired into TrioSettings and HomeStateModel; scoring is skipped when disabled
- Add "Quick Bolus" entry to Feature Settings between Bolus Calculator
  and Meal Settings
- Move all quick bolus UI out of HomeRootView into focused fragment files
  (QuickBolusView, QuickBolusInfoView, SlideToConfirmView)
- Fix bolusFormatter minimumIntegerDigits 0→1 so 0.5 renders as "0.5"
- Replace "Deliver" with "Enact" throughout quick bolus UI and strings
- Use safeAreaInset for slide control so subtitle text is never cropped
  on small screens (iPhone mini)
