refactor(appkit-ui): remove unused recharts ChartContainer, drop recharts dep

The shadcn ChartContainer/ChartTooltip/ChartLegend/ChartStyle wrapper
(src/react/ui/chart.tsx) was exported from @databricks/appkit-ui/react but unused
anywhere in the repo, and it imported the entire recharts library via
`import * as RechartsPrimitive`. The echarts-based components in react/charts are
the charting API, so recharts can be dropped entirely.

This removes dead, unused code — no shipped or used API surface changes.

- delete src/react/ui/chart.tsx and its barrel re-export
- remove recharts from peerDependencies and devDependencies
- drop the decorative recharts chart from the drawer example
- regenerate component docs (removes ChartContainer.mdx, updates examples registry)
