Add --blueprint to plot_dashboard_stress

[teh-cmc]

Adds a --blueprint flag to plot_dashboard_stress that will force it to send a blueprint that sets a neat 5s window query for all plots.

Blueprint(
    Grid(*[
        TimeSeriesView(
            name=p,
            origin=f"/{p}",
            time_ranges=VisibleTimeRange(
                "sim_time",
                start=TimeRangeBoundary.cursor_relative(offset=rr.TimeInt(seconds=-2.5)),
                end=TimeRangeBoundary.cursor_relative(offset=rr.TimeInt(seconds=2.5)),
            ),
        )
        for p in plot_paths
    ]),
    BlueprintPanel(state="collapsed"),
    SelectionPanel(state="collapsed"),
)
