NAS-132643 / 24.10.2 / Rework ping logic

[bvasilenko]

Testing:

Enter login page, authenticate, and then logout. Watch messages sent over websocket in browser's network log

Expected results:

1. ping should be sent only when user is authenticated. In other words, ping should not be sent on "public" pages, such as login screen
2. call core.ping should be done instead of sending { msg: 'ping' }
