feat: update city display and database schema

- Change city name display to localized name in both index and show views
- Modify schema to use bigint for certain foreign keys
- Correct country codes in seeds for accurate data representation

These changes improve the handling of city names, ensuring they are displayed in the appropriate localized format and ensuring well-typed foreign key relationships in the schema.
