PipelinePanel: wrap card content in a Column so stages stop painting over the headline

SonarCard's Surface lays un-wrapped siblings in a Box, so the whole
processing panel (teal headline, gray elapsed/note text, stage rows,
progress bar) drew stacked on one line — the 'text overlapping while
summarizing' garble, visible only mid-job. Every other card call site
wraps its content; this was the one that didn't. Headline also gets
weight(1f, fill=false) + maxLines/Ellipsis so it can't collide with
the elapsed/ETA text at narrow widths.
