🐛 Fixed Portal not appearing on 404 pages

closes: https://github.com/TryGhost/Ghost/issues/12413

- portal should be included if there is no context so that it appears on 404 pages
- having this inside the if (context) block was an oversight
- we want to chain the accent color style block, so we move this to the end to make that possible
