Added visualizations to the run summary page to show optimization insights.

• Optimization history plot - to show how we converged on the optimal config
• Parameter importance plot - to show which parameters had the the most impact on optimization.
• Parameter slice plot - to show more granular insights into parameter values that performed the best.

Updated optimization logic to directly select the only element from a parameter candidate list if there's only 1 possible candidate based on user selections.

Added back protocol to the css and javascript import statements to avoid the CORS blocking issue in Chrome
