Turn the agent-install playbook into a full provisioning + maintenance
path. Solves the bootstrap chicken-and-egg: first contact uses an
operator-supplied password (one run, never stored), which creates a
dedicated `steward` login account with NOPASSWD sudo + Steward's managed
public key. Every run thereafter connects as `steward` with the managed
key — fully unattended (scheduled prune, agent updates).
- core/crypto: generate_ssh_keypair() — ed25519, OpenSSH formats.
- settings: ansible.ssh_public_key (non-secret, displayed) + ansible.ssh_user
(default steward); to_ansible_cfg extended.
- settings UI + route: "Generate managed key" (private encrypted, public
shown to copy) + SSH-user field.
- executor: build_bootstrap() writes a 0600 vars file (-e @file) for the
per-run user/password — never argv, never DB, never logged; drops the
managed key when a bootstrap password is given; --user floor from the
global ssh_user when no override.
- runner.trigger_run: pass-through `connection` kwarg, deliberately NOT
persisted on AnsibleRun.params (password stays out of the DB).
- bundled/host_agent/provision.yml: create steward user + authorized_keys
+ /etc/sudoers.d/steward (visudo-validated) + agent install.
- host_agent: /provision route + "Provision a fresh host" card (bootstrap
user/password; injects pubkey + user + token as space-safe JSON hostvars).
- Dockerfile: add sshpass (Ansible shells out to it for password SSH).
- tests: keypair generation + build_bootstrap (secret stays off argv).

Global Ansible credentials, applied to every run (manual + alert-triggered):
- core/settings.py: ansible.ssh_private_key / become_password / vault_password
(plaintext at rest, masked in UI — encryption tracked in #580) + host_key_checking
(default off); surfaced via to_ansible_cfg into app.config[ANSIBLE]
- executor.py: pure build_credentials() materializes creds into a 0600 temp dir
(--private-key, --vault-password-file, become via -e @vars-file so the password
never hits argv) cleaned up in finally; pure ansible_env() sets
ANSIBLE_HOST_KEY_CHECKING. build_ansible_command stays param-only
- settings/routes.py + ansible.html: admin-only Credentials section, masked-update
(blank keeps current, explicit Clear checkbox), reload app config on save
- tests: unit (build_credentials per cred + none; ansible_env toggle); integration
vault round-trip (ansible-vault encrypt a vars file, run via executor with the
vault password, assert it decrypted)
