Introduce a `docker-compose.yml` to define the services for backend and database with health checks. Add Alembic configurations for database migrations and an initial empty migration. Include backend-related Docker setup with an entrypoint script for database migration execution.
This commit includes configurations and boilerplate code for both frontend and backend. The frontend uses Next.js with Tailwind CSS, while the backend is built with FastAPI. Various essential files like `tsconfig.json`, `requirements.txt`, and `.gitignore` have been added to kickstart the development process.
