silverwind 643bd38051 fix: size mermaid iframe by the diagram's aspect ratio (#40046)
Mermaid scales diagrams wider than the markup column down to its width,
but the iframe kept the unscaled viewBox height, leaving a large blank
area below them.

The iframe now uses a CSS `aspect-ratio` capped at the viewBox height,
so it follows the rendered diagram on any width and resize without
measuring, which keeps diagrams in collapsed `<details>` working.
Diagrams that don't scale (`useMaxWidth: false`) keep the fixed height.
