Re-enable Firebase token sync respecting simultaneous UWB interactions to among 3 connections per device
Unfortunately the graphics I showed actually demonstrate the maximum number of devices allowed, so we can't attempt to start interaction among everyone in the game, but rather limit it to people who are nearby on GPS/through local network multi-peer.
Since MPC works over eduroam, Firebase token sync is currently disabled. When enabled, MPC should take precedence over Firebase peers.
