- api_client.dart: connectTimeout 10s → 60s — Flutter was cancelling
requests to /recommendations after 10s while the server waited for
OpenAI, causing 'context canceled' on the server side
- product/repository.go ListForPrompt: expires_at is computed via
(added_at + storage_days * INTERVAL '1 day'), not a stored column;
wrap in CTE to reference it by alias in SELECT/ORDER BY
- home/handler.go getExpiringSoon: same fix — use CTE to compute
expires_at before filtering/ordering by it
