fix: support tool result image format in Control UI

Browse Source 
Add support for the backend tool result image format
{ type: "image", data: "base64...", mimeType: "image/png" }
in the extractImages function.

Previously, Control UI only recognized the Anthropic standard format
with a nested source object. This fix allows browser screenshots and
other tool-generated images to display correctly in the chat interface.
