Fix wrong country shown for sub-national organizations

[poojavenkatapuram]

Update the organization page to display the parent organization instead of the country for sub-national entities.

Falls back to showing the country when no parent organization exists. This change only affects display logic and does not modify data.

Fixes #576

I am sorry, but I think you have misunderstood the relationships between countries and their parts. First, they are likely never modeled in Wikidata with a parent organization property, and it is also likely that countries are modeled in different ways. But that's beside the point because we don't need to look that up; it is defined in the country query.

Thanks for the clarification, that makes sense.

I see now that inferring hierarchy via parent organization is not reliable
and that the intended logic is already defined in the country query /
generator output.

I’ll revisit the implementation and adjust it to rely on the country query
instead of organization relationships.

Please let me know if you have a specific file or query in mind that I should
base the change on, and I’ll update the PR accordingly.
