Make roles configurable from the staff page

In reference to this snippet:

    async (accessToken, refreshToken, profile, done) => {
        const hacksuMembershipURL = `https://discord.com/api/v10/users/@me/guilds/632634799303032852/member`;
        const data = await fetch(hacksuMembershipURL, { headers: {"Authorization": "Bearer " + accessToken } })
            .then(res => res.json())
            .catch(_ => null);
        
        const roles: string[] = data?.roles ?? [];
        if (roles.some(role => ROLES?.includes(role))) {
            return done(null, {...profile, isLeader: true});
        }
        return done(null, false);
    })

This is a quick hack to setup a bunch of discord roles that can access and manage the staff site. At some point I had plans to make it so this was configurable from the staff page. It would be an nice feature to have. I can probably implement this myself at some point if nobody picks this up.

Maybe this even leads to a "better auth management" solution for this platform: role management for all users, session management, forced password updates, etc..

EDIT: I guess it also makes sense to completely move to just using Discord for auth, since it's easier to manage the roles there

@Monster0506 this might be something you want to take on if you're bored. If you don't, I'll get to it at some point
