From a host's edit page, an operator can run a playbook against just that host
via an ephemeral one-host inventory — no need for the host to exist in a source
inventory.
- ansible/sources.py: pure host_inventory_content(host) -> '<name> ansible_host=<addr>'
- executor.start_run: optional inventory_content written to the temp dir and used
as -i (overrides inventory_path); cleaned up with the creds dir
- hosts/routes.py: POST /hosts/<id>/run-playbook (operator) — validates source +
playbook, builds the ephemeral inventory, starts a user-triggered run, redirects
to the live run detail; edit page gets the ansible source list
- hosts/form.html: 'Run Ansible playbook against this host' panel (shown when
editing an existing host and sources exist) — source + playbook + extra-vars/
tags/dry-run (no --limit; single host)
- tests: unit host_inventory_content; integration runs a hosts:all/connection:local
playbook against the ephemeral inventory and asserts inventory_hostname
