Fix: Cloning now correctly copies COA values when default COA creation is enabled.

[Gitesh307]

Fixes #4825

Cloning a Collection Object with CO_CREATE_COA_* enabled was creating a new blank CollectionObjectAttribute instead of preserving the original attribute values, which meant cloned COs did not produce an exact copy. The fix updates the auto-creation logic in scoping.ts to only generate a new COA when the record is newly created and has no existing attribute, while skipping COA creation during clone operations. As a result, cloned COs now retain their original CollectionObjectAttribute values, and new COs still automatically receive a COA when appropriate.

Note : Observed in tag v7.10.0; not reproducible on main. Please advise backport to the appropriate v7.10.x or v7.9.x.

Checklist

• Self-review the PR after opening it to make sure the changes look good and
  self-explanatory (or properly documented)
• Add relevant issue to release milestone

Testing instructions

• Verify that cloning a Collection Object with existing COA values retains those values in the cloned record instead of creating a blank attribute irrespective of CO_CREATE_COA in remote preferences.
