BOLT-1267 Phase 1 — unit-less stepped event curve preview in EventDrawer

blocked

Priority: 2

New EventCurvePreview.tsx rendered above ActionBuilder in EventDrawer. Pure SVG (no chart lib), unit-less Y axis (+1 discharge / 0 idle / -1 charge), gaps = 0. Mode colors from COMMAND_MARKER_COLORS. Reserve floor as shaded band across the discharge half labelled with each discharge action’s reserve %. Snapshot tests on segment generation. Phase 2 wires real device kW + SoC, deferred.
