Introduced a new `frontend` service in `docker-compose.yml`, complete with build, healthchecks, and networking. Added a multi-stage Dockerfile for the frontend, a `.dockerignore` file, and a startup script to wait for the backend. Updated Next.js configuration for Docker compatibility and added API type definitions.
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.
