To clean up the multi tool page and make the pdf adapters more re-usable the style for them was moved to separate pages that are inserted into head when the adapter is created.
Turn the div adapters into injectable files so that each PdfContainer can be customized. And the adapters can be used in different PdfContainers as well.
The positioning of the insert pdf buttons and the direction icon of the move page buttons are tied to the language direction, to fix this we retrieve the language direction from the document and use this to reverse some logic/elements for RTL languages.
To correctly center the pdfs inside of the scrollable div we need a wrapper, ideally the 'safe center' flex-direction would be used, but this is not yet supported by most browsers.
