[BUGFIX] Count elements in clipboard correctly when pasting all

In the record list, the method generating the clipboard paste
confirmation along with the "Paste in clipboard content" counted in a
wrong fashion since #106032, as the amount of records is not handed in
anymore.

Since that single method cannot determine what to count without context,
a new internal enum `CountMode` is introduced that instructs how
elements in the clipboard should get counted.

Resolves: #106474
