2fa1672edf fix(assembly): guard onChanged against solver during document restore
Some checks failed
Build and Test / build (pull_request) Has been cancelled
Details 
During document restore, PropertyLinkList::Restore sets the Group property
on AssemblyObject, triggering onChanged → updateSolveStatus → solve →
validateNewPlacements. At this point joints reference objects that haven't
been restored yet, causing a null pointer dereference (SIGSEGV).

Add an isRestoring() guard to skip solver invocation during restore,
matching the existing pattern in AssemblyLink::onChanged().
