- Integrate Alembic for managing database schema migrations, replacing the previous SQL schema management. - Update the FastAPI application to synchronize interface definitions at startup. - Modify the Docker Compose command to run Alembic migrations before starting the API. - Enhance the Makefile with new commands for database migration and revision management. - Remove outdated SQL schema and seed files, transitioning to a more dynamic migration approach. - Add initial migration scripts and configuration for Alembic, ensuring a structured database evolution.
