Adding an LXC/VM with a parent_id pointed at a Proxmox node that is
NOT in container_mode set extent:'parent' anyway, confining the node
to the parent's ~140px bounding box with no way to drag it out.
Nesting is now gated on the parent's container_mode in both places:
App.handleAddNode no longer sets parentId/extent itself (it seeds an
absolute position and lets addNode decide), and addNode strips any
stray parentId/extent when it isn't nesting. New children of a real
container still land at the container's top-left.
