- Networks: network_service (list w/ subnet/containers/in-use/owning-stack, create bridge/macvlan/ipvlan/overlay + optional subnet/gateway/internal, delete with default-network guard, prune) + routers/networks.py; real Networks page replaces the placeholder. - Fix: local stacks can now be deleted from the UI — Delete button on stack detail (with optional keep-files-on-disk) and a trash action on stack cards, via a shared ConfirmDialog. (Backend DELETE existed; no UI surfaced it.) Verified: py_compile, frontend tsc build, live network list smoke test (defaults flagged, compose nets + in-use detected); main 104 routes.
