Feature: #47135 - Paste icons available at pasting position and use modal now

See forge#47135

Description

As soon as the normal clipboard contains an item, a single paste icon becomes available in the page module. The icon is located at each possible pasting position directly besides the [content +] buttons. When the user clicks on the icon, a modal pops up to have the user confirm the action. Depending on the clipboard mode this will either be "Copy" or "Move" together with the title of the item in the clipboard and a "Cancel" button.
