fix(realtime): throttle connections based on subscription attempts

[filipecabaco]

🔍 Description

throttle connections based on subscription attempts

What changed?

added a throttling mechanism using a buffer for servers and local storage for browser where we throttle subscriptions to prevent useEffect load and errors.

Why was this change needed?

currently we see users reaching easily the limits of their accounts due to what are potentially errors when it comes to disconnecting and unsubscribing channels and, by consequence, kill the websocket.

this usually happens due to bad useEffect practices.
