Add Live Activity for level sensor (surfaces on CarPlay automatically)
Replaces the ActivityKit boilerplate with a real lock screen/Dynamic Island UI driven by live pitch/roll readings, toggled from the leveling device's detail screen. Since iOS 17 shows any running Live Activity on CarPlay's dashboard without a dedicated CarPlay app entitlement, this covers the requested CarPlay use case without one. Also fixes the widget extension never being embedded into the app (missing Embed Foundation Extensions build phase and target dependency), which meant no widget or Live Activity could ever have rendered regardless of code changes.
