fix: GROQ filter no longer requires researchInteractionId for non-researching docs

Docs reaching research_complete without deep research (disabled or failed)
were invisible to check-research. The ID requirement now only applies to
'researching' status — research_complete, infographics_generating, and
enriching docs are always picked up.
