infra: devpi role for launchd on indri, retire from minikube

- New ansible role ansible/roles/devpi installs devpi-server +
  devpi-web into a uv-managed venv at ~erichblume/devpi/venv,
  initializes the server-dir on first run (via 1Password root
  password fetched in playbook pre_tasks), and runs as a LaunchAgent
  bound to 127.0.0.1:3141.
- Caddy: switch the pypi.ops.eblu.me backend from the tailscale
  ingress to http://localhost:3141.
- Playbook indri.yml: add pre_tasks to fetch the devpi root
  password from 1Password and include the new role.

The minikube StatefulSet has been scaled to 0 to free memory; the
ArgoCD app + manifests will be removed in a follow-up commit once
the launchd service is verified.
