Scope
Approximately 30 Greenlandic postcodes exist in total. This PR ships the 10 largest / most-canonical settlements with confident municipality assignments. Smaller villages (e.g. 3961 Uummannaq, 3962 Upernavik, 3962 Tasiilaq, 3970 Pituffik) can land in follow-up PRs once the schema is exercised.
