Added detailed logging to help diagnose empty tenant list issues:
- Log demo_session_id, demo_account_type, and tenant_count
- Log actual tenant IDs returned
- Log when demo user detected but no session ID
This will help identify:
1. If demo_session_id is being passed correctly from gateway
2. If tenants exist in DB for the session
3. Timing issues (API called before session fully initialized)
