test(charts): add Pie chart + usePieInteractions tests

Cover the shared Pie chart and its helpers/hook:
- utils: scaled font size, arc geometry, colour lighten/fill dimming
- usePieInteractions: marker toggle, label isolate/reset, hover focus,
  hidden-slice guard, localStorage persistence + rehydration
- PieArc: leader-label threshold, label truncation, enter/leave/click
- PieCenterLabel: numeric/unit split
- Pie: no-data state, arc-per-slice rendering, legend, layout per position,
  hide-on-marker-click

Adds a global ResizeObserver polyfill to jest.setup.ts (alongside the existing
IntersectionObserver one) since visx's useTooltipInPortal requires it.
