Setup Podman and Podman Compose for local development

Add comprehensive Podman configuration for local development:

- docker-compose.yml: Main compose file with all services (PostgreSQL, RabbitMQ, API, Frontend)
- docker-compose.dev.yml: Development-specific overrides with hot-reload
- Dockerfile.api: Backend API service Dockerfile
- Dockerfile.frontend: Frontend Next.js service Dockerfile
- Updated Dockerfile: Podman-compatible production build with better layer caching
- .env.example: Environment variable template
- .dockerignore: Exclude unnecessary files from builds
- Makefile: Convenient commands for common Podman operations
- scripts/db/: Database initialization scripts directory
- Updated README.md: Comprehensive Podman setup and usage documentation

Features:
- Rootless Podman support with SELinux compatibility
- Development mode with volume mounts for hot-reload
- Health checks for service dependencies
- Proper build stage optimization
- All services networked together
