Add graph for Composition and XRD

[undera]

Composition has a reference to composite resource definition, via compositeTypeRef field. The improvement is to enable "Relations" tab for composition view drawer and XRD drawer and display relation there.

The task needs both backend and frontend work. Can be done via separate PRs by different people.

Backend needs to use same trick with full=1 query parameter, to list:

• for composition, the XRD it refers to
• for XRD, all compositions that refers to it
