Lucas Smith 1647f7c4a0 fix: correctly insert fields on rotated pages (#1183 )

## Description

PDFs can have pages that are rotated, which are correctly rendered in
the frontend. However, when we load the PDF in the backend, the rotation
is applied which causes issues when we want to insert fields.

To account for this, we swap the width and height for pages that are
rotated by 90/270 degrees. This is so we can calculate the virtual
position the field was placed if it was correctly oriented in the
frontend.

Then when we insert the fields, we apply a transformation to the
position of the field so it is rotated correctly.

**Test document with 0/90/180/270 rotated pages**
