Simplify Docker Compose to single-file architecture

- Convert multi-file overlay approach to single docker-compose.yml
- Use environment variables for dev/production differences
- Remove complex network configuration conflicts
- Align with framework principles: simplicity over complexity
- Production config via .env.production file

Benefits:
- No more network subnet conflicts
- Single source of truth
- Framework-compliant architecture
- Easier maintenance and debugging
