Object: Cmd/Ctrl+Alt+Shift+2 locks inside clip groups and isolation, with no menu item

object.lock.unselected is now reached by its key and as a command only:
the Object > Lock > Unselected Artwork menu item is removed, and the
command stays in the registry, the shortcut editor and automation.

In a partly selected clip group or compound path it now locks the
unselected members, the clipping path included, and leaves the container
and the selected members unlocked. It locks unselected guides while Lock
Guides is on. Hidden art and art on a locked layer stay unlocked, and a
selected layer's art counts as selected.

With a selection in isolation mode the command is enabled and locks only
the unselected art inside the isolated group. The other Lock and Hide
items keep their isolation behavior.

Lock and Hide still share one selector. A lock flag on it selects the
clip group, compound path and guide cases above; Hide > Unselected
Artwork keeps its behavior, and a test covers both directions.
