Deprecation/Removal: Remove Flash-based user photo upload functionality in `verify_student`

This is one of those things that for all practical purposes has been broken for years:

I plan to remove it pretty much immediately. This is just a bookkeeping DEPR for documentation purposes.

But as always, if for some reason you’re still using Flash upload on your site, please comment here or in the DEPR ticket.

Thank you.

Hah, nice find.
