CSS: convert all topology inline styles to modifier classes

Replace style= attributes on topology wire/node elements with semantic
modifier classes:
- topo-vc-wire--wan, --10g, --mgmt (wire colour semantics in CSS)
- topo-v2-host--bus (bus-section node size constraint)
- topo-legend-item--offrack already done in prior commit

Zero inline styles remain in the topology section.
