Feature Request: Better Model Identification for BYOK Providers

I'd like to suggest an improvement to the BYOK (Bring Your Own Key) model selection experience.

When using models from different providers through BYOK, all of them are currently labeled as "Custom" in the model picker. This makes it difficult to distinguish which provider a model belongs to, especially when multiple providers offer models with similar names.

At the moment, the provider or group name only becomes visible after selecting the model, which requires extra clicks and can be confusing.

It would be very helpful if the model selector could display additional information directly in the list, such as:

Provider name (e.g., OpenAI, Anthropic, Google, OpenRouter, etc.)
User-defined group name
Custom tags or labels
Provider icons or badges

This would make model selection much faster and reduce the risk of accidentally choosing the wrong model when multiple BYOK providers are configured.

Thank you for considering this improvement.

从 /chat 模型选择器开始，追踪 BYOK 模型在选择器中的表示和显示方式。比较可用的 provider、group、tag 和 icon 信息，然后定义一个一致的可见标识符，在无需进行选择的情况下区分已配置的 provider。完成标准是：用户能够在选择之前可靠地区分相似的 BYOK 模型。
