Returns a unified camera (NSDKCamera) for the current frame when one is available.
In live mode uses the current ARFrame's camera; in playback uses the current playback frame's camera.
Returns nil if no frame is ready. Use this so callers do not need to branch on session mode for view/projection/viewport.
