Make the run status legible

The status Markdown rendered at body size in a block Gradio caps with an
inline `overflow: auto`, so a one-line phase label sat in a 23px sliver with
a scrollbar. Give it an id and style it as a banner: 1.15rem text, padding, a
secondary fill, and a min-height that clears the progress overlay Gradio draws
over a running event, with overflow forced back to visible.

Gradio 6 moved `css` from the Blocks constructor to `launch`.
