Foundation for the Ansible automation milestone (#37) — makes the existing
manual playbook runner actually executable and the schema automation-ready.
- pyproject: [ansible] extra (full ansible package, batteries-included, pinned)
- Dockerfile: pip install .[ansible]; add openssh-client for remote runs
- models/ansible.py + migration 0012: AnsibleRun.triggered_by now nullable so
automated (alert/schedule) runs need no human actor
- ansible/routes.py + run_detail.html: show 'Triggered by' (username or 'system')
- CI: integration lane installs .[dev,ansible]; new tests/integration/
test_ansible_foundation.py runs a real connection:local playbook end-to-end,
asserts success+output, and round-trips a NULL-triggered run
No extra-vars/limit/credentials/scheduling here — those are their own #37 tasks.
