**feat(docker): add docker-compose for multi-service setup**

Introduce `docker-compose.yml` to orchestrate services for local development. Include configurations for PostgreSQL, Redis, MinIO (S3), Mailpit, backend, and frontend. Simplify setup with predefined environment variables, volumes, and dependencies, ensuring streamlined service management and integration.
