thread-events
Create a ThreadEvent.
For ASSIGN/UNASSIGN, delegates to the service layer which owns the idempotence rules, edit-rights validation and the undo window. For IM, persists the event via the serializer and then re-syncs MENTION rows.
Returns 204 when the service decides nothing was new (every assignee already assigned, full UNASSIGN absorbed by undo, …).
