test(08-01): add failing tests for Calculator widget and registry constraints (RED)

- calculator-widget.test.tsx: 5 behaviour tests (render, arithmetic, div/0, keyboard, decimal) - widget-registry.test.tsx: DASH-11 structure check for all 8 widget types including new Phase-8 types - Both suites fail (RED baseline) — implementation does not exist yet
