chore: Add PDF config for layoutset

[standeren]

Description

Implements support to set an existing layout as dedicated PDF. Setting it to PDF assigns a PDF-icon to the accordion and moves it to the bottom of the pages-panel in order to separate it from the order. Also implements a unset functionality moving the page back to order and removing the icon. If trying to convert a layout to pdf while there exists a pdf already a modal is shown with the options to convert the existing pdf back to a layout page or deleting it.

This PR also improves the way new layouts are named by simply checking that the autogenerated name does not exist in either order or pdfLayoutName.

Nice, thorough work!
It's great that you notice and clean up unneeded code along the way 😄

I only have some nitpicking comments about the language 😊
