Update docs and diagram for extended multi-fabric topology

Browse Source 
- README: rewritten node inventory, AS map, addressing plan
  (management, Lo0/Lo1, P2P, hosts), VNI/RD/RT tables, control-plane
  summary and end-to-end Campus <-> DC test procedures through the
  Core (VRF gold stitching).
- hosts/README: document the two new Campus host configurations.
- assets/arista-evpn-fabric.svg: new three-zone layout (Campus, Core,
  DC) with legend.
- evpn-lab.clab.yml.annotations.json: reposition nodes and add zone
  labels so the ContainerLab graph matches the extended topology.
