feat: add Z-Wave node types to add/edit node modal

Z-Wave (controller/router/end device) types existed in the model, theme
accents, default icons and the custom-style editor, but were missing from
the node Add/Edit type selector, so they could not be placed manually like
Zigbee nodes. Add a Z-Wave group and default mesh-radio nodes to no status
check (not IP-reachable), matching Zigbee behaviour.
