Improve display of PDF attachments; Add support for full resolution

[bronwyncombs]

Is your feature request related to a problem? Please describe.

The existing user preference to display attachments as either thumbnail or full resolution does not apply to .pdf attachments, these always display as a thumbnail from gallery and on forms.

Attachment Gallery:

On Record:

Screen.Recording.2024-06-27.at.1.03.56.PM.mov

When full resolution, attachments resize along with the dialog but thumbnails remain the same size regardless of dialog size. This makes it effectively impossible to adequately view .pdf attachments within the software without opening in a new tab.

Describe the solution you'd like

Support full resolution displays of PDFs in preferences; either changing the existing pref or adding a separate one for .pdf displays

Describe alternatives you've considered

Some databases (https://ichthyology.specify.ku.edu/specify/) have attachment forms that display pdfs in the pdf viewer, although the source of this behavior is unknown.

I believe implementing this would be a more ideal solution as the pdf area is resizable with dialog and the user can use +/- to select the preferred zoom.

Additional context

Ichthyology DB doesn't show or allow adding an attachment view def in visual editor:

But the XML can be found in the XML editor view:
