Include exception message in ErrorAnalysisCard subtitle

[shrutipatel31]

Summary:
The exception message is now displayed in the ErrorAnalysisCard subtitle, allowing users to immediately see the reasoning (e.g., why an analysis is not applicable) without needing to expand the error card.

Previously, the subtitle only showed a generic message like "AnalysisNotApplicableStateError encountered while computing ParallelCoordinatesPlot." Now it shows the actual exception message, such as "AnalysisNotApplicableStateError: Experiment has no trials", providing immediate context.
