Release this client only with prairie-server#183.

A mixed deployment can reject every affected WebSocket upgrade. Deploy the matching server revision before this client, or make the server accept both identifier sets during rollout. This applies to prairie.playback-control.v2, prairie.room.v2, prairie.events.v2, and the prairie.ticket. prefix.

@shared/src/commonMain/kotlin/org/prairieserver/prairie/network/PlaybackRealtimeClient.kt
at line 270:
The v2 WebSocket identifiers can reject upgrades during a mixed deployment;
coordinate these client identifiers with the matching server revision, or update
the server to accept both identifier sets during rollout. At
shared/src/commonMain/kotlin/org/prairieserver/prairie/network/PlaybackRealtimeClient.kt
lines 270-270 and 290-290, apply the coordinated change to both playback
identifiers; at
shared/src/commonMain/kotlin/org/prairieserver/prairie/network/WatchTogetherRealtimeClient.kt
lines 106-106 and 148-148, apply it to both room identifiers; and at
shared/src/commonMain/kotlin/org/prairieserver/prairie/network/apiv2/EventsSocketV2Api.kt
lines 76-76 and 97-97, apply it to both event and ticket identifiers.
