Rendering issues should be displayed in the preview

[koppor]

As user, I copy the rendered reference manually to Microsoft Word or LibreOffice. Thus, I need properly rendered references - and JabRef needs to warn me if the rendering has some quirks.

Quirks can be:

• entry incomplete
• "Magic mapping" as discussed at Entry preview not rendering the citation properly  jabref#8372

Solution proposal:

• Wrong place is underlined and a click brings me to the entry editor at the appropriate place
• The place could also offer "fix" action (AKA cleanup - see Cleanup actions. Move action for issue, number, eid, pages fields. jabref#8413)
