fix: use Part.Rotate() in PlateView to avoid mutating shared Programs

Browse Source 
RotateSelectedParts was calling Program.Rotate() directly on shared
Program instances, bypassing Part's copy-on-write (EnsureOwnedProgram).
Parts created via CloneAtOffset share the same Program, so rotating one
part would rotate all parts with the same reference.
