Add actor tracking for status changes and use unified timeline

- updateTaskStatusWithActor logs status_change events to agent_events
- Worker uses Junior actor for status changes - Jr review uses
System/Human actors appropriately - CLI task update uses Human actor
- Remove task_activity table schema (migrated to agent_events) -
addComment now inserts into agent_events with event_type='comment'
