fix: opaque overflow menu, add Update button to cockpit and assistant headers

The IncidentHeader overflow menu was see-through due to bg-elevated on
bg-card. Switched to bg-card with shadow-xl and fixed-scrim dismiss
pattern matching production FlowPilotSessionPage. Replaced unicode
ellipsis with MoreHorizontal icon + aria-label. Added Update button
(StatusUpdateModal) to IncidentHeader and FlowPilotPage header bar
for feature parity with production.
