Replace the desktop 8-column table with card-like mobile rows on phones,
following the ImagesTab pattern. Each row shows a 44px checkbox for compare
selection, a severity dot, truncated image ref with trigger and timestamp
meta, count tags (total vulns + fixable, at most 2), and a chevron.
Secret/config-only scans use the FINDINGS dot and suppress the clean tag,
matching the getSeverityKey classification from severityStyles.
Extract a shared HistoryStateMessage component to deduplicate the
loading/error/empty state blocks between the mobile and desktop branches.
