chore(docker): refactor Docker configuration for environment variables and database initialization

- Updated docker-compose.yml to use environment variable fallbacks for configuration.
- Modified Dockerfile to streamline database initialization using Prisma migrations directly.
- Removed init-db.js script as its functionality is now integrated into the Docker CMD.
