fix(ui): port retail partial stack transfers

Browse source 
Route the selected stack quantity through retail GetObjectSplitSize semantics, send exact split-to-container and split-to-ground actions, and keep the original object in place until the server publishes the newly guided stack. Cover selection scoping, wire bytes, container placement, and world drops with conformance tests.
