feat(assets): add SVG node set, node-type config and sample document

Water supply group (source, tank, pump, valve, junction, consumer) and
power group (generator, transformer, switch, load) with port configs,
physics property specs, pipe/cable/insulation catalogues and a demo
waterworks document.
