chore: migrate from docker compose to kubernetes deployment

- Replace Docker Compose setup with Kubernetes manifests for deployment
- Simplify Dockerfile to use PHP's built-in server instead of nginx+supervisor
- Add Makefile with build and deploy commands for local development
- Update environment configuration for production deployment
- Remove docker-specific configuration files (nginx.conf, supervisord.conf)
