Add status screens for order venues status screens

[vincevd1]

This adds a status screen that automatically switches between the original status screen for shifts and a music screen to see what is currently playing.

From what I have seen you do not get logged out of the current session as long as the browser stays open which is the case with thaliedje. So we can just log in with an account with no privileges and put this link on.

I hooked up a monitor in noord to show this screen.

Code looks fine, will have to see it live to say something about the styling

Styling of the music screen looks like the following:

Large text because it has to be able to be seen on the monitor from far away. I could include the next song from the queue as well if needed

Hey Vince! Thanks for the MR. I have two suggestions:

• I've created OAuth2 support for one of the status screens, you can find the PR here.
• I think it would be better if we would put this all into one screen without the need for refreshing. I would do it the following way:

1. Check if a music player exists, if it does, tell the template to also render a music player.
2. In the template, check if an active shift exists, if it does, display and refresh that.
3. If no shift is active, switch over to displaying the music player. If no music player exists, display a message saying that there is no active shift).

I think this is cleaner than refreshing the page (I also got into an infinite refresh loop when testing).

@vincevd1 I made some small changes again. I removed the dedicated active shift endpoint in favor of using the list shift endpoint with query parameters

Nicely done @vincevd1! Just one small thing and we can merge this 😄 You may also overwrite the old status screen if you want to.
