Add Tryton synchronization for CatalogSale

- Add external_id field to CatalogSale model for tracking synced sales
- Create migration 0047 for external_id field
- Add TrytonCatalogSale and TrytonCatalogSaleLine classes for Tryton RPC format
- Add send_catalog_sales_to_tryton() method to SaleTrytonService
- Create CatalogSalesToTrytonView API endpoint (POST)
- Register endpoint at /don_confiao/api/enviar_catalog_sales_a_tryton
- Add test for external_id field functionality
- Catalog sales sync to same Tryton model as Sale (model.sale.sale.create)
- Differentiated by reference 'don_confiao_catalog X' and description 'Venta de catálogo'
- Filters only catalog sales without external_id to avoid duplicates
