fix: topology — all servers dual-homed 10G+1G, show mgmt band

All rack servers (and large1 on table) have both a 10G link to USW-Agg
and a 1G management link to Pro 24 PoE. Update topology:
- Move all 6 hosts into single row (including large1)
- Update sublabels to "10G+1G" for all nodes
- large1 dashed-border (off-rack) with "table · 10G+1G"
- Add dashed amber "1G mgmt (PoE)" horizontal band above hosts
  to represent the PoE switch management connections
- 10G primary fan-out lines still drop from Agg switch above
- large1 primary line rendered as dashed green (off-rack run)
