fix(openlist):Add error handling and stability improvements for OpenList service

- Add try-catch blocks around OpenList startup/shutdown operations
- Implement global uncaught exception handler for JNI/native crashes
- Add synchronization and duplicate startup checks in OpenList.startup()
- Ensure data directory creation before service initialization
- Add proper error logging and user feedback for service failures
- Set foregroundServiceType to dataSync for Android compliance
