fix(ios): initialize surface props in BottomSheetSurfaceComponentView

[JaMinsane]

Problem

Fabric requires every RCTViewComponentView subclass to initialize _props with its concrete default props.

BottomSheetComponentView already follows this contract, but BottomSheetSurfaceComponentView did not. In an iOS debug build using React Native 0.87.0, mounting BottomSheetSurfaceView for a non-null surface therefore triggered the following assertion:

`RCTViewComponentView` subclasses (and `BottomSheetSurfaceComponentView` particularly) must setup `_props` instance variable with a default value in the constructor.

This caused a ModalBottomSheet to terminate the application before becoming visible.

Fix

This PR imports the generated props header and initializes _props with BottomSheetSurfaceViewProps in initWithFrame:.

This matches the existing implementation in BottomSheetComponentView and satisfies the Fabric component-view contract.

There are no JavaScript API or Android behavior changes.

Verification

• Reproduced the crash on iOS with React Native 0.87.0 and Fabric.
• Built and launched the affected application with this change.
• Verified that the affected ModalBottomSheet opens without the native exception.
• Verified that the application's other bottom-sheet flows continue working.
• Confirmed that BottomSheetSurfaceViewProps matches the component descriptor used by BottomSheetSurfaceComponentView.
