restructure: eliminate box-in-box production architecture

- Move production configs from /opt/aitbc/production/config to /etc/aitbc/production
- Move production services from /opt/aitbc/production/services to /var/lib/aitbc/production
- Centralize production logs in /var/log/aitbc/production
- Remove redundant /opt/aitbc/production directory
- Add production launcher script at /opt/aitbc/scripts/production_launcher.py
- Update production services to use system configuration paths
- Create comprehensive production architecture documentation
- Achieve proper FHS compliance with clean separation of concerns
