Bring main website up to date with main branch

[slmnio]

The main slmn.gg site uses the latest release which is over 100 commits old now. I've been hesitant to bring so many new changes to live, but it's about time.

The big change is that authentication is now live on the development server. Most of the return paths look like they should be fine, but it's nothing some quick patch releases couldn't fix.

Major changes coming to 1.17 are:

• Discord authentication
• New action system for API requests
• Overhauls to the auction system (even more are needed)
• Lots of new overlay changes
• Lots of new internal data systems changes (though since the data server is always the latest commit it's been in production for a while)
• Hero recolouring beta

This issue will track the deployment of the new version to see if anything breaks.

First release only updated the dev server, a force redelivery looks like it's done the job. Now to test things to see if it breaks.

There's an issue in the server/src/discord/auth.js file with a TODO which is required for this to work. It needs to do a similar thing to the client side to send over the correct redirect_uri in the request

Maybe fixed in 8f30b75

Confirmed fixed, now to check other parts of the website to see if there's any cors errors or anything
