The pull-to-refresh gesture logic was already correct (verified by driving
real pointer events through it); what was missing was overscroll-behavior
on the scroll container, so on real touch hardware the browser's own
native overscroll could take the gesture over before it hit the threshold.
"Beleg hochladen" now opens a dialog instead of the native file picker:
drag a PDF in at the computer, paste it from the clipboard on the phone
(copied out of a mail), file picker kept as a third route. All three
sources share one upload path.
