Refactor NavisworksRootObjectBuilder.cs for improved context extraction

- Extracted the GetContext method to retrieve the name and path of a model item
- Replaced calls to GetDisplayPath with calls to GetContext for consistency
- Updated CreateNavisworksObject and ConvertBase methods to use the extracted context information instead of finding meaningful ancestor names
- Updated the "path" property in the returned NavisworksObject instances with the extracted path
