Fix 1 (A): move row height constraint from min-height on tbody tr
(CSS no-op on table-row) to height: 32px on td (works on table-cell).
Fix 2 (A): table header text-[11px] -> text-[12px] to align with
documented caption scale.
Fix 3: add aria-controls + id to Tabs buttons; wrap active tab content
in role="tabpanel" + aria-labelledby in EngagementDetailPage.
Test: add aria-controls/id assertion to Tabs.test.tsx (234 total).
