Foundation for autonomous fleet management.
cloud_credentials stores encrypted API tokens per cloud provider.
worker_profiles bundles the env vars that get rendered into
/etc/warmbly/worker.env at install time.
provisioning_templates is a customizable saved config — every Hetzner
option the admin form exposes lives here, so the cheapest-US-single-IP
setup is a one-click pick once you've saved it.
provisioning_jobs is the state machine (pending -> creating_server ->
creating_ips -> assigning_ips -> setting_rdns -> installing ->
verifying -> completed | failed -> rolling_back).
provisioning_policy is per-provider budget caps + the auto_provision
toggle the scale loop checks.
decision_log records every automated action so admins can audit what
the system did and why.
