fix: OpenSearch status field mismatch, adopt RouteFlow flows prop

Fix admin OpenSearch page always showing "Disconnected" by aligning
frontend field names (reachable/nodeCount/host) with backend DTO.

Update design system to v0.1.10 and adopt the new multi-flow RouteFlow
API — error-handler nodes now render as labeled segments with error
variant instead of relying on legacy auto-separation.
