Model display in message box

[codelonesomest]

I suggest displaying the profile model name we set, such as kilocode/claude-sonnet-4, instead of the default format kilocode:anthropic/claude-sonnet-4.

Reason for preference: When using an OpenAI-compatible API provider, the same model can be hosted under different base URLs. The current model selection button is too small to clearly indicate which model and provider or base URL is being used. Showing the custom profile model name provides better clarity and helps users quickly identify the specific model configuration.
