fix: allow anonymous chat connections when auth fails

- Modified chat auth failure handler to proceed with WebSocket connection
- Generates anonymous user_id and session_id using crypto.randomUUID()
- WebSocket handler already supports anonymous connections (creates UUIDs if not provided)
- Removes error notification and retry loop that prevented chat from working

This allows chat to work publicly without requiring authentication,
which is the expected behavior for public bots.
