"""UI construction mixin for the main radar control window.
Layout is intentionally split into two independent plot surfaces:
- single `PlotWidget` for B-scan heatmap rendering;
- stacked magnitude/phase `PlotWidget`s for pass-through traces.
`_set_plot_mode()` switches between these surfaces via `QStackedWidget`.
