fix(pages,services): make thematics & topics pages usable again

When I refactored the fetchers and convertors in #f111685 I forgot to
convert WPThematicPreview and WPTopicPreview so the thematics and
topics pages was broken.
I also:
* removed the ToC added by error in #70b4f63
* fix heading styles
* fix website url in topics pages
