Migrate to tailwind

[Betree]

Fix CaptainFact/captain-fact#243

This PR is an experiment using refactoring tools at scale, with the intent to:

1. Entirely remove Bulma and SASS
2. Remove the custom icomoon font system
3. Start deprecating CSS modules and styled-components
4. Remove unnecessary redux reduces
5. Introduce Typescript
6. Introduce Tailwind/ShadCN and migrate part of the codebase to these new components
7. Give a fresh look to the website!

Still to do:

• Fix scrolling (left/right cols) on video debate
• Figure a better strategy for global animations/styles
• Code cleanup
• Responsiveness
• Typescript errors
• Typescript CI job
• Final QA
