Replace 3 fragmented environment views (2 hardcoded stubs + tables component)
and D3.js force-directed map with a single unified topology page at
/environments/overview. The page renders an interactive SVG graph using
ElkSharp compound layout (regions as parent containers, environments as
child nodes, promotion paths as directed edges with gate labels).
Backend: new GET /api/v2/topology/layout endpoint that builds ElkGraph
from topology read model, runs ElkSharp compound layout, returns enriched
positioned nodes and routed edges.
Frontend: topology-graph.component.ts (SVG renderer with zoom/pan/select),
topology-graph-page.component.ts (filter bar + graph + detail side panel).
Deleted: environments-list-page, platform-setup-regions-environments-page,
topology-map-page, topology-regions-environments-page. Routes consolidated
from ~12 paths to 6 with backward-compat redirects.
