Pull request overview

Adds motion-gesture support (shake + flip) to WebView in-apps by introducing a sensor-backed MotionService, exposing new bridge actions to start/stop monitoring, and emitting motion events back to JS.

Changes:

• Introduced MotionService to detect SHAKE and FLIP gestures (including flip position transitions).
• Added WebView bridge actions: motion.start, motion.stop, and outbound motion.event.
• Added unit tests for shake detection behavior and flip position resolution.
