Describe the bug

Description

// AppHost
IResourceBuilder<ParameterResource> deepSeekApiKey = builder.AddParameter("deepseek-api-key", true);
IResourceBuilder<ConnectionStringResource> deepSeekConnectionString = builder.AddConnectionString(
    "deepseek",
    connectionStringBuilder => connectionStringBuilder.Append(
        $"Endpoint=https://api.deepseek.com/;Key={deepSeekApiKey};Model=deepseek-chat"));

// Consumer
builder.AddKeyedOpenAIClientFromConfiguration("deepseek").AddKeyedChatClient("deepseek")
// or
builder.AddKeyedOpenAI("deepseek").AddKeyedChatClient("deepseek")
// more? such as Azure?

For keyed client, they won't apply the configured connection string. It will keep using the OpenAIClientOptions with default named option. I think the results depend on whether you've configured the default named option, if not, it will use the default value of the OpenAIClientOptions. And the connectionstring, key and model are incorrect for keyed clients.

Cause

We need to manage named option here, and I did not take further investigation for azure related, not sure whether they are using this.

Expected Behavior

Make sure keyed OpenAI related services can be configured normally.

No chance for 9.31? If there is a chance, I'll try to make a pull request.
