[BUG] Files with the same name overwrite each other in sync

Which app is your issue for

What happened?

When you create several documents the same day and they receive the same file name by your name template (= today's date), only the latest file gets exported with "Sync document PDFs" enabled or it overwrites the others.

So files should not be allowed to have the same name right in the app and get a number appended to their title when there's already file with the same name, and this check should also be what happens when the app tries to export to the selected folder, it shouldn't overwrite anything but automatically adjust the name. And when there's already today.pdf and today01.pdf, the next file has to be renamed to today02.pdf and so on.

Code of Conduct

• I agree to follow this project's Code of Conduct

Start by tracing where the app generates document names and where the “Sync document PDFs” export writes to the selected folder. Check how existing same-name files are handled, including sequences such as today.pdf and today01.pdf. Done means same-day documents receive distinct names in the app and export no longer overwrites existing files.
