fix: errors on Responses API connections are not shown or not kept after a reload (#31439)

Browse source 
With a connection set to the Responses API, when the provider reported a reply as failed, the error showed while streaming but was gone after a reload, leaving an empty reply. Some other provider errors never showed up at all, not even while streaming. Both kinds of error now show up and are still there after a reload, the same as on Chat Completions connections.

Fixes #31433
