fix: unreliable websocket functionality (#144)

* increases timeout

* refactor: reuse constants for redis db

* avoid closing connection on pong error

* fix: prevent electron from pausing timer executions

Our pings could be paused when our app is backgrounded.

* refactor: remove unnecessary refs

* fix: presence unreliable within same pod

It was broadcasting presence changes to other pods, but not notifying
clients connected to the same pod
