Dashboard Performance - Make components Pure or Memorize them

### Background
Components can often needlessly re-render when receiving the same props due to how react does comparisons between previous props and next props. Making class components `PureComponent` or wrapping function components in `React.Memo` can solve this problem for components that re-render frequently but have props that don't change Frequently

### Potential Components:
- [ ] `NavHeader`
- [ ] `InnerView` (inside visualization/components/View.tsx)
