feat(hub): drop files and folders onto Files to upload them

Into the folder on screen, under the Upload button's rule. A name already
there, or one the node would refuse, cancels the whole drop with a message.
Folders are recreated level by level; files go out a few at a time. The
in-flight upload guard is keyed by folder and name.
