Draft: judging: finalist vote dry-run

⚠ This MR is not supposed to be merged to main ⚠

Judges will dry-run the finalist voting during their training sessions, so this MR is just to have an endpoint for them in the DEV environment. Data has already been imported (no emails, they should login using their username).

Please, keep it up to date, especially in case of commits affecting judging.igem.org
