Prevent Students from joining Breakouts/Waiting room before requesting help through the queue

[TwoLettuce]

Overview

Students sometimes put themselves into the waiting room or breakout rooms without having clicked the button and submitting the modal for help or passoffs. This is problematic because if they don't join the queue, we can't track the stats and we end up with incomplete statistics for the students and have less information about how to help them. This is definitely a bigger issue in-person, but it at least is possible to prevent this kind of thing online.

Suggested Fix

Give a student a role once they have joined the queue online. That role has permissions to join the waiting room and breakout room VCs, but @everyone does not have permission to do so. Remove the role from the student if they leave the queue themselves, or after they finish getting help. Be careful with server role setup permissions in server_script.py.

Note that this would also require editing how the server is setup with setup_script.py, making the related voice channels require more restrictive permissions and an additional role to keep track of.

Makenna also suggested sending messages to students when they join a breakout/waiting room without being in the queue instead of enforcing roles (would be better in case the bot gets shut down - we'd have to create new non-permission-locked voice channels to interact with the students).
