feat: docker and docker-compose support

Introduced a Dockerfile and compose.yml to allow the application to run inside a Docker container. This removes the need for local system-level dependencies and offers a more predictable environment for the app. README.md was updated to include Docker-related instructions and an additional environment variable `DOCKER_DB_FOLDER` was added on top of existing ones for Docker support.
