* feat: add click-to-preview for images in AI chat
Uploaded images in AI chat messages can now be clicked to open a
full-size lightbox preview. Clicking the overlay or the image again
dismisses it. Uses the existing Radix Dialog component.

* fix: use standard dialog style for image preview with close button
Replace transparent borderless overlay with proper windowed dialog that
has a background, border, and the built-in close button (X) in the
top-right corner. Remove focus ring that caused the blue border.

* fix: add title bar with filename and blurred backdrop to image preview
- Show filename in dialog header with border separator
- Add overlayClassName prop to DialogContent for per-instance overlay
customization (e.g. backdrop blur, custom background)
- Apply semi-transparent black background with backdrop-blur on overlay

* fix: align title and close button vertically in image preview
Adjust header padding and close button position so the filename and
X button sit on the same visual line.
