Gemini model missing icon #1247
Description
Background
In the model selection interface, the Gemini model does not display its corresponding icon, affecting recognition and consistency.
Issue
In the model list, the Gemini entry shows an empty space or a placeholder instead of the correct icon.
This creates inconsistency with other models that do have icons.
Expected Behavior
Add the official Gemini icon.
Ensure all model icons follow a consistent size and style.
