Draft: #3530258 An idea: calculate starting only when needed
Update PublishReview slice to support merging individual autoSave hashes. Refactor baseQuery in preview, componentAndLayout, and assetLibrary services to inject only the relevant autoSave hash and clientInstanceId for all mutations. Ensure all APIs merge new hashes into the slice when received from the server. Remove manual passing of autoSaves/clientInstanceId in hooks and mutations.
Closes #3530258
