feat: Add AreaGeoSeeder for importing geographic data from external database

- Create AreaGeoSeeder to import area geo data from external zones table
- Add field mapping: zonecode→AreaCode, zoneclass→Class, zonename→AreaName, parentzoneid→Parent
- Support same-server external databases using direct SQL queries
- Register seeder in DBSeeder for inclusion in main seeding workflow
