fix(orchestration): resolve repositoryIdentity in listing snapshot

Pre-existing projects never got grouped in the sidebar because
getListingSnapshot (the Phase 1 bootstrap used to paint the sidebar)
omitted repositoryIdentity. New projects happened to work because
project.created events carry the resolved identity, but rows read at
startup only had whatever the listing snapshot populated — which was
nothing. Mirror the resolver call from getSnapshot so every listed
project has identity and logical-project grouping can key off it.
