Fix figma image references

Some files have stuff like this:

```
const backgroundImage = "https://www.figma.com/api/mcp/asset/72b8d852-b32d-4ef9-8172-702438e2ed8e";
```

Ideally, we want the image included in the codebase (or some proper file storage) and not referencing the figma file. Fix all of this.
