Visualises the chat read-receipt metrics added with the read-receipt feature (the dashboard was deferred there per the owner): posted rate by kind, the unread backlog (chat_unread_messages gauge), and the publish-to-read latency (chat_read_duration — average by kind plus overall p50/p95). Mirrors the game-domain dashboard's structure; the file provider auto-discovers it.
