Shopify: Failed Single-Order Imports Now Surface Instead Of Silently Doing Nothing

Manually importing an older Shopify order used to look like nothing happened — no order, no error, no note anywhere. The failure was always there: Shopify blocks import of orders older than 60 days without an extra permission grant, and that failure was getting silently dropped instead of shown.

Failed imports now log a clear line against the Shopify integration explaining what happened — whether the order couldn't be found, the connection needs to be reconnected, or it's a temporary issue that will retry on its own. Actually pulling in orders older than 60 days still needs a permission change on our end — that's a separate follow-up.
