Fix DB design, Entity, Repository

[zigzagdev]

what i changed

• Added a pivot (join) table to the database schema.
• Updated the entity to support multiple countries and to expose state party (country) codes.
• Extended the repository’s insert logic so it can register multi-country (transnational) World Heritage sites, not just single-country properties.

Pull Request Overview

This PR implements multi-country support for World Heritage sites by adding a pivot table relationship and updating the entity structure. The changes enable storing and retrieving transnational World Heritage properties that span multiple countries.

Key changes:

• Added a Country model with seeder containing all UNESCO state party codes and regional data
• Implemented a many-to-many relationship between World Heritage sites and countries through a pivot table
• Extended the WorldHeritageEntity to handle multiple state party codes with metadata (primary country, inscription years)
