fix(rgi): diagnostic download route — tries multiple URL patterns

Download route now:
- Calls fileVisibility with documentTypeId (if provided)
- Calls confirmOnView with documentPk
- Tries 3 different download URL patterns until one works
- Add &debug=1 to see diagnostic results instead of downloading
- Page now passes documentTypeId in download link
