Add SEO view to normal page editing mode

[Sebobo]

Currently the editor has to switch to the Yoast SEO view manually and has to change back and forth when updating content.
It would be good to have an overlay or a display of a part of the SEO data already when editing the site.
This could be done with the new Neos UI.

• Integrate analysis nicely into the inspector or create additional "SEO bar"
• Check how to rerender the content in the background after content changes to update the analysis in a way that doesn't make the backend slower
• (Optional) quick link to SEO preview mode

This should be fine now as is with the addition of the yoast inspector view.
