test/hil: show pass/fail/skip counts above the HIL report table

Prefix each rig's hil_report.md matrix with a one-line tally
(passed / failed / skipped) so the number of failed tests is visible at a
glance in the PR comment without scanning the table. A metric-string cell
(e.g. throughput) counts as a pass; blank/not-run cells are excluded.
