[Storybook] Update styles to be more accurate to prod (#1945)

## Summary:
Perseus Storybook in its current state does not accurately
reflect how these component look in prod.

A couple things are added here to fix this:
1. Stories are wrapped with the `framework-perseus` class.
2. Webapp styles are imported
  - `box-sizing: border-box` in particular affects all the
    spacing (margins and padding)

Issue: none

## Test plan:
- Go to http://localhost:6006/?path=/docs/perseus-components-number-input--docs
- Confirm that the inputs have rounded bordersa, and the
  "mini", "small", and "normal" stories show different sizes.
- Go to http://localhost:6006/?path=/story/perseuseditor-widgets-interactive-graph--interactive-graph-ray
- Scroll to the start coordinates panels
- Use the dev tools to confirm that the width is 308px
  (previously 336px)
