Subject: [PATCH] [TD] make more pointers to the UI std::unique_ptr

addendum to PR #4293

(as noted in https://github.com/FreeCAD/FreeCAD/pull/4271#discussion_r554673632
the pointer to the UI should be a unique pointer.

This PR does this for remaining TD dialogs that don't already use a unique_ptr.)
