style(ui): align markdown code block chrome

Update fenced markdown code blocks to use square corners and compact headers matching the tool-call code output treatment.

The shared markdown styles now remove code block radii, shrink the header to the same 1.6rem control height, and restyle the copy action as a compact icon-only header button while keeping the accessible copy label available to screen readers.

Validated with npm run build:ui; Vite completed successfully with existing warnings about JSX import source, mixed static/dynamic imports, and large chunks.
