Retire Docker-based tools to unused/

Docker is not installed on pet630, so neither of these can run there:

- docker-idrac.sh is the container-based alternative to the ipmi-fancontrol
  scripts, which remain in service.
- webnut-docker/ is the web UI for the NUT daemon. NUT itself is still
  running on the host; only this front end is retired.

The gitignored .env moves with the compose file and is still excluded at the
new path.
