jamey 5c2f70ce44 add shipping costs with live exchange rates and country detection ... Shipping rates fetched from Printify during product sync, converted to GBP at sync time using frankfurter.app ECB exchange rates with 5% buffer. Cached in shipping_rates table per blueprint/provider/country. Cart page shows shipping estimate with country selector (detected from Accept-Language header, persisted in cookie). Stripe Checkout includes shipping_options for UK domestic and international delivery. Order shipping_cost extracted from Stripe on payment. ScheduledSyncWorker runs every 6 hours via Oban cron to keep rates and exchange rates fresh. REST_OF_THE_WORLD fallback covers unlisted countries. 780 tests, 0 failures.
