fix: resolve TypeScript strict mode errors failing CI

- StatusDot: status → variant (correct prop name)
- Badge: color="muted" → color="auto" (valid BadgeColor)
- AreaChart: remove stacked prop (not in AreaChartProps)
- DataTable: remove defaultSort prop (not in DataTableProps)
- TopError → ErrorRow with id field (DataTable requires T extends {id})
- slaCompliance: type assertion for runtime field not in TS schema
- PunchcardHeatmap Scatter shape: proper typing for custom renderer
