fix(node-ui): clarify context graph entity labels

[Jurij89]

Summary

• Adds a shared layer-aware noun helper so Working Memory and Shared Working Memory render items as entities while Verified Memory continues to render Knowledge Assets.
• Removes WM/SWM-facing asset wording from layer stats, detail headers, layer list empty states, action copy, and the provenance summary without changing the later tab IA scope.
• Improves memory entity label derivation so name/title predicates win and raw urn:dkg:extraction:<uuid> values fall back to a readable extraction label.

Related

• Follow-up to fix(node-ui): canonicalize context graph layer counts #604.
• Implements Context Graph rollout PR 2.1: M1 + S8.
• Leaves S1 tab IA and the Verified Memory -> Verifiable Memory rename for the later IA PR.

Test plan

• pnpm --filter @origintrail-official/dkg-node-ui exec vitest run test/ka-detail-label.test.ts test/use-memory-entities-labels.test.ts test/use-memory-entities-counts.test.ts test/project-view-navigation.test.ts

• git diff --check
• pnpm --filter @origintrail-official/dkg-node-ui run build
• pnpm --filter @origintrail-official/dkg-node-ui run build:ui
• Local Vite shell smoke at http://localhost:5175/ui/: dashboard and WM/SWM/VM layer pages loaded; empty WM/SWM pages showed Entities and VM showed Knowledge Assets. Local API returned expected 500s for missing/empty local graph data, so populated-node validation remains manual.
• Local PR reviewer round against pr-diff.patch: no actionable comments.

🟡 Issue: entity.label starts life as shortLabel(uri), and shortLabel still returns the full string for colon-delimited URNs. That means this guard short-circuits the new fallback for most unnamed urn:* entities, so labels like urn:test:source will stay raw instead of becoming a readable tail. Consider treating the default URI-derived label as non-authoritative here (for example by comparing against shortLabel(entity.uri)) before returning it.

🟡 Issue: this adds dc/elements/1.1/title to entity-label resolution, but the graph views still hard-code a smaller predicate allowlist. Entities that only have this title predicate will render with a friendly name in lists/detail panes and a raw URI in graph cards. Please thread the same predicate list into the graph label config, or centralize the list so these views stay consistent.
