Repurpose the Maximize2 button in SchematicViewer as a fullscreen toggle (was reset-zoom; percentage label is now clickable for that). Add matching fullscreen toggle to WaveformViewer alongside the scope button. Both use a shared useFullscreen hook for Escape-to-exit and body scroll lock. In fullscreen mode, the SVG canvas and plot areas fill the viewport with proper dimension tracking via ResizeObserver.
