Enhance analytics charts with interactivity and skeletons

Added interactive active segment highlighting to the customer segments pie chart and improved the monthly revenue/orders chart with gradient areas and labeled axes. Replaced loading spinners with ChartSkeleton components for a more consistent loading state. Refactored SkeletonLoaders to accept className and improved code style.
