- Replaced Black, isort, and Flake8 with Ruff for linting, formatting, and import sorting.
- Updated `requirements.txt` to include Ruff and remove replaced tools.
- Added `Makefile` to streamline development workflows with commands for linting, formatting, type-checking, testing, and cleanup.
Moved Alembic files into the `app/alembic` directory and updated related paths. Consolidated database configuration in `config.py`, leveraging environment variables and ensuring centralized management. Updated Docker Compose to include `.env` files, providing a more consistent environment setup.
