Service map: real call edges from traces

The service map went from disconnected dots to an actual topology.

  • Call edges from trace spans. Caller→callee edges are derived from cross-service Client/Server span pairs (/api/v1/service-map), so the map shows real dependencies today — OBI's built-in network feature enriches un-instrumented edges when enabled.
  • Readable layout. The graph now accounts for label size, so service names no longer overlap; edges show direction and call volume, red on errors.
  • Auxiliary traffic excluded from node sizing and edges by default.
