What

Two new error messages were added for authentication failures: one specifically for Microsoft Foundry, and one for generic gateway refusals. Both share a new suffix noting that credentials are managed via environment variables.

Why

This gives clearer, more specific error text when authentication fails through a Microsoft Foundry or gateway setup, making it easier to understand that the issue relates to environment-managed credentials.
