fix: align default values of map UI option props with Naver Map iOS SDK (#141)

- Changed prop types of isShowCompass, isShowScaleBar, isShowZoomControls to WithDefault<boolean, true>
- Ensures default value is true, matching the SDK's default behavior
- See: https://navermaps.github.io/ios-map-sdk/reference/Classes/NMFNaverMapView.html
