Ckeditor preview - show serif or sanserif fonts accurately

[mariacha]

Describe the bug
Some content types use a serif font for the body, but this is not indicated during editing preview. This ticket would find those content types/rules and replicate them during editing.

This is updated on develop. Articles should have serif fonts:

as should publications:
https://develop-wriflagship.pantheonsite.io/node/65410/edit?destination=/admin/content

while other pages should have sans-serif:

The fonts and styling look good @mariacha , thanks!

For a future ticket, we might want to fix the caption under the table , see example here: https://develop-wriflagship.pantheonsite.io/events/2024/4/health-facility-electrification-lessons-developing-countries -- not sure we had that as an option before the new version, but currently the caption is above the table and isn't styled correctly (in the editor or frontend)
