test(e2e): confirm the Save name prompt before awaiting the download

#458 made Save prompt for a file name (via a dialog) in browsers without the
File System Access picker — which these specs delete in addInitScript. The
save-and-reopen specs clicked Project → Save and waited for a download that
never fired, because the name-prompt dialog now intercepts the save, so both
tests hit the 60s timeout (failing on main too). Accept the pre-filled default
name and confirm the dialog so the download proceeds.
