Extract shared helpers into a new RimCorrelationBarChartTools namespace so RimCorrelationPlot and RimRftTornadoPlot share a single source of truth for: - highlightSelectedParameterBar and the click-to-parameter-name lookup - the axis-label format, abs/sort-value math, and the addBarEntry call (with the "legendText must equal parameter name" convention) via addCorrelationBar Also enable click-to-select on RimCorrelationPlot: use the parameter name as the bar chart title so click-to-select works, and recolor the selected bar via a new HighlightBarColor field, mirroring the pattern used in RimRftTornadoPlot.
