🔧(dev) configure bureautix proxy for image builds

Builds through the Docker API of the Podman service receive none of the
proxy variables in their RUN steps and fail systematically because of
the proxy rejection. Plain HTTP connections are also rejected by the
proxy with a HTTP 405 method error.

- Passes http_proxy, https_proxy and no_proxy from the shell as build args
- Make the Debian mirror of the agents image a build argument and
  override it for bureautix to force https usage
