LT-22691: Preserve trailing ViewNode fields when applying an override

[mark-sil]

ViewDefinitionOverrideApplier rebuilds every node when it applies a patch, but its CloneWith and CloneWithId helpers stopped short of the ViewNode constructor's last three optional parameters. Omitting them let the defaults win, so EnumStringList, VisibleWritingSystems and ToggleValue were stripped from the whole tree as soon as a project carried any override -- a single SetVisibility operation was enough.

		// Every node is rebuilt on apply, so a clone that omits a field strips it tree-wide once
		// any override exists. These three fields are outside ToSnapshot(), so the empty-patch
		// test misses it.

and aren't covered by the EmptyPatch test
