Replace android.os.Looper by android.os.HandleThread to prevent blocking main thread

[JoBolNex]

This PR improves the handling of background threads for legacy phone state listening on Android versions below S (API 31). Key changes:

• Replaced the manual Looper management with a dedicated HandlerThread
• Added proper cleanup of the HandlerThread by implementing quitSafely() when stopping the listener
• Moved HandlerThread to a class property to ensure proper lifecycle management and prevent potential memory leaks
• Removed the blocking Looper.loop() call which could cause issues on the calling thread

I applied this fix using patch and fixed my issue with IncomingCall UI not showing but will show if I "restart" my expo server. Kudos!
