broadcast: broadcasts sometimes disable themselves after two minutes

[Trek Hopton]

I was trying to start the KI stream but after ticking enabled on the broadcast page and waiting a couple minutes, the box was unticked. Looking in the cloud logs, I saw this: (It was at 13:01 13/3/2024)

2024/03/13 02:31:05 (name: KI Oyster Reef by Kingscote Area School, id: JFNHPfxpXXA) failed to start broadcast: could not create broadcast: could not create broadcast: could not broadcast stream: could not insert broadcast: googleapi: Error 403: User requests exceed the rate limit., userRequestsExceedRateLimit response: {0 map[]}, resp: {0 map[]}

This is explainable by youtube limiting us in the case the broadcast manager spams youtube with create broadcast requests, which only happens when we have bugs.
