feat(#49): add product provenance (suppliers, organizations, geography)

- Country, Department, Municipality models (municipality unique per department)
- Organization and Supplier models, Supplier links to organization and municipality
- Product.suppliers M2M to link products to one or more suppliers
- Authenticated CRUD APIs for organizations, suppliers, countries, departments and municipalities (write only for administrators)
- product_provenance domain data embedded in sale/catalog summaries (public and authenticated)
- seed_geography endpoint (admin, idempotent) and scripts/seed_geography.py using pycountry + DANE municipalities CSV
- TDD tests for models, API permissions/CRUD and summary provenance data
