feat: add Chart, Dashboard, DashboardWidget schema and migration

- Add Prisma models for Chart, Dashboard, DashboardWidget
- ChartType: area, bar, line, pie, big_number only
- Remove DashboardStatus and WidgetType (widgets are always charts)
- DashboardWidget requires chartId, remove content/type fields
