fix: #36023 - Omnichannel widget fails to show new messages

[preeder]

fix: Livechat widget can lose connectivity on websocket (issue 36023 - #36023)

We do not know any way to test the fix. It takes a very specific virtualization environment created to emulate unidirectional communications for a short period of time, similar to what cell phones can experience in fringe coverage. See bug 36023 for the way we created this environment in Hyper-V. While we do not absolutely know that this is what causes our 0.019% of cases where the visitor has expressed the inability to see the messages from the agent, we do know that this is a potential cause. We also know that the proposed fix eliminates this cause.

Proposed changes (including videos or screenshots)

This changes ensures that a client based failure on the ddp-client websocket causes a reconnection of the websocket used for server based events, including new message events.
