feat(node-ui): rebuild context graph overview IA

[Jurij89]

Summary

• Implements PR 2.3 / S1 + S2 + N8 from the Context Graph UX plan: the view switcher now follows the pipeline IA, with memory layers grouped before Subgraphs and Query Catalogue in More.
• Rebuilds the Context Graph Overview as a summary-only surface with role/access badges, shared StatStrip stats, one Knowledge Pipeline, and links into WM/SWM/VM instead of embedding duplicate layer pages.
• Adds the linked Context Graph primer, including a direct /ui/context-graph-primer restore path, and completes the user-facing Verifiable Memory terminology sweep across adjacent node UI memory surfaces.
