feat: Complete dark mode support for all dashboard components

- OrchestrationSummaryCard: Full dark mode support with CSS variables
- InsightsGrid: Replace Tailwind classes with theme-aware CSS variables
- All dashboard components now properly adapt to light/dark themes
- Skeleton loaders use theme colors for seamless transitions
- ProductionTimelineCard filters for today's PENDING/ON_HOLD batches

All dashboard components now use CSS variables exclusively for colors,
ensuring proper theme adaptation and consistent user experience across
light and dark modes.
