Introduce a new environment variable, `DATA_FILES_DIR`, for configuring static file storage. Updated `docker-compose` files to mount the host directory and propagate the variable. Implemented FastAPI `StaticFiles` to serve files from this directory under the `/files` route.
The `frontend_dev_modules` volume was redundant and is no longer being used in the development workflow. This change simplifies the `docker-compose.dev.yml` file by eliminating unnecessary configuration.
Replaces the named volume `frontend_dev_modules` with a direct path `/app/node_modules`. This change simplifies development setup and ensures consistency across environments.
Added the `env_file` directive to both `docker-compose.yml` and `docker-compose.dev.yml` to load environment variables from a `.env` file. This ensures consistent environment variable management across different configurations.
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.
