Split Outputs into Published Research and Resources sections

[rdhyee]

Context

Hana's wireframe note: "Divide into 2 main sections: Published research (publications, conference slides) and Resources (Zenodo community, Github repository)"

Current state

The Outputs section lumps everything together: conference talk video, metadata model slides, publications, Zenodo community, Github repositories.

Work needed

• Split into "Published Research" (publications, conference presentations)
• And "Resources" (Zenodo community, Github repositories, data files)
• Update nav to reflect new structure (under "Related Research/Resources" per wireframe)

Priority

Quick reorganization — minimal new content needed.
