Add ChartContainer, ChartConfig, ChartTooltip, ChartTooltipContent
primitives ported from ShadCN's chart pattern. Refactor all 3 chart
locations (dashboard, funnels, uptime) to use CSS variable-driven
theming instead of duplicated CHART_COLORS_LIGHT/DARK objects.
- Add --chart-1 through --chart-5, --chart-grid, --chart-axis CSS vars
- Remove duplicated color objects from 3 files (-223 lines)
- Add accessibilityLayer to all charts
- Rounded bar corners on funnel chart
- Tooltips use Tailwind dark classes instead of imperative style props
