Improve type-safety in data storage

[Dinika]

1. Improve the type interface for the files object in DataPanel to include path:

            files.push({
              ...item,
              // @ts-ignore
              path: getPathForChildResource(resource, item),
              _self: resource._self ?? item._self,
              resourceId: resource['@id'],
            });

2. Remove @ts-ignore comments. (except the ones for "Error". We have to update ts for that).
3. Add "distribution" as a field of "Resource" in nexus sdk
