Implement Redis event bus partitioning to improve performance and scalability in multi-server deployments.
Previously, all Hypha server instances subscribed to all Redis event channels (
event:*), leading to high traffic and unnecessary message processing. This PR introduces a partitioning mechanism where each server only subscribes to events for clients it directly manages (event:*:server-id) and a general broadcast channel (event:*:broadcast). This significantly reduces Redis network traffic and server-side processing overhead, enhancing horizontal scalability.
