Added support for optionally running the wot-relay service as a Tor hidden service. Updated the docker-compose.tor.yml file to conditionally enable clearnet access, based on the `ENABLE_CLEARNET` environment variable. Updated the README.md file with instructions on how to use this feature.
This commit updates the Dockerfile to use a more docker-friendly approach. Instead of cloning the repository inside the Dockerfile, it now copies the files from the host. It also sets some fixed environment variables and uses a .env file for the rest.
The docker-compose.yml file now uses an .env file for more convenient environment variable management. It also maps volumes to the host, allowing you to change the paths of the `db` folder and `templates` folder.
The README.md has been updated with new instructions reflecting these changes. It now includes instructions for running the Docker container in the foreground or background, and for updating the relay.
