ui: datastore: use safe destroy as base for dialog

only ask the name of the current NS, not the full NS path to avoid
too long input requirements on deep levels.

needs a few smaller hacks, ideally we would pull out the basic stuff
from Edit window in some EditBase window and let both, SafeDestroy
and Edit window derive from that, for better common, in sync
features.
