wip: Bunch of changes for v4

From the top of my head (but I'll write this up later):

- We keep the info about the designs in the design
- We use a new about.json file for this
- The auto-generated data.mjs file is no more
- Linedrawings we use in the design picker use the front
- Linedrawings should respect square aspect ration
- Migrated components to use the 'tw-' prefic for tailwind CSS classes
  to avoid conflicts with docusaurus styles
