Feature Request: add Storybook

[roushou]

Describe the solution you'd like

The development workflow can be improved by using Storybook which provides isolated testing, accessibility checks, interaction testing and more.

Some useful addons:

• a11y
• source
• visual testing (requires Chromatic)
• figma

Network requests can be mocked using a service worker (also useful for happy paths). It does require some additional steps to keep mocks in sync.

Also update CI to catch bugs and regressions.

Describe alternatives you've considered.
