Add team and person work-completed performance graphs

[Modsofthenation]

Summary

Adds work-completed performance graphs for the team and for individual people, using existing delivery rollup / team-performance / rating-trends APIs (no new backend).

What’s new

Team performance (/team-performance)

• Overview metric: total work completed (issues done + PRs merged; story points when known)
• Chart: Work completed by person (horizontal bars)
• Chart: Delivery vs overall scatter (spot high ratings with thin delivery)

Person dossier (/team/:id → Performance)

• Window mix bars (issues done / WIP / PRs / reviews / bugs)
• Multi-cycle delivery series
• Overall rating trend when rated cycles exist
• Existing delivery rollup numbers stay below the charts

Sprint pulse

• Work completed in window throughput chart by person (achievement counts)

Shared SVG/CSS chart helpers live in apps/ui/src/components/charts.tsx (no chart library added).

Test plan

• Demo unlock → Team performance: work-completed bars + delivery scatter appear for people with synced delivery
• Open a person dossier → Performance section shows mix + cycle series (and rating trend if rated)
• Sprint pulse → Throughput section bars match people table achievement counts
• pnpm --filter @prm/ui typecheck
