Add Image viewer overlay and fix max-width of images in chat#122
Conversation
Add ::deep .markdown-body img rules to ChatMessageList.razor.css so images in rendered markdown scale to their container (max-width: 100%), preserve aspect ratio (height: auto), and have rounded corners (border-radius: 6px). This prevents image overflow in chat messages and improves visual consistency.
Introduce a full-screen image viewer (overlay, close button, CSS) with zoom/pan support including mouse wheel zoom, mouse drag, and touch pinch-to-zoom/pan. JS is initialized in index.html with delegated clicks on chat images to open the viewer and exposes window.__imageViewer. Also add cursor: pointer to several message/image containers in ChatMessageList.razor.css to indicate clickability.
