[Fix] websocket connecting and patchDB connection monitoring (#1738)

* refactor how we handle rpc responses and patchdb connection monitoring

* websockets only

* remove unused global error handlers

* chore: clear storage inside auth service

* feat: convert all global toasts to declarative approach (#1754)

* no more reference to serverID
