mesh-cli requires the console's endpoint and writes its address

nox now reaches the mesh through this machine's console, so the module
requires mcp-endpoint and writes the bound address to /etc/mesh-cli/console
rather than trusting a fixed port. No invokes: mesh-cli has no bus account,
and one nothing dials would only be minted.
