- Add resolvePropertyIcon mock to BaseNode tests
- Reset mockZoom in top-level beforeEach to prevent test bleed
- Use prop.key instead of index as list key in BaseNode properties
- Extract isValidConnection into useCallback in CanvasContainer
Extract onBeforeDelete into useCallback to avoid new fn ref each render.
Fix useThemeStore/useCanvasStore mocks to call the selector fn rather
than ignoring it, and reset mockZoom in beforeEach.
- Wrap borderWidth in useMemo to avoid re-computing on unrelated renders
- Replace hardcoded 1px in boxShadow with borderWidth so glow ring
matches border thickness at all zoom levels
- Add useViewport mock + 4 zoom-scaling tests to BaseNode.test.tsx
