Event catalog

Each row below is one possible (entity, event) pair on the ws.user.v1 envelope. The catalog mirrors x-tradara-event-catalog in tradara-core/services/ws-server/api/asyncapi.yaml — if this page disagrees with the spec, the spec wins. The data payload of each event matches the response schema of the linked REST endpoint, so the same parser can be used for hydration and for live deltas.
