Created reusable `Base`, `UUIDMixin`, and `TimestampMixin` in `base.py`. Added a `User` model with attributes, relationships, and database configurations in `user.py` to establish a foundation for user-related features.
Moved environment variables to .env.template for better management and updated docker-compose files to use them. Added separate docker-compose.dev.yml for development, a Makefile for streamlined commands, and split backend Dockerfile into development and production stages. Updated .gitignore to include new changes.
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.
