authentik: boot-persistent quadlet conversion with deploy handler

The compose-era authentik trio died at every boot (rootless podman does not
auto-start bare containers). Convert the trio to Quadlet units installed by
deploy-remote.sh into ~/.config/containers/systemd/, enabled + WantedBy=
default.target:

- 3 unit files under dankclaw/authentik/quadlet/ (postgres -> server -> worker
  ordering via Wants=/After=; secrets stay in the git-ignored host .env,
  expanded by systemd at start time exactly like the gitea units)
- deploy_authentik() handler: install units, daemon-reload, retire stale
  compose-era containers only while units are inactive, enable once, then
  start in dependency order with podman-health gates between stages
- compose.yaml: authentik service definitions retired to a comment pointing at
  the quadlet dir (same pattern as searxng/open-webui/gitea/caddy)
- tests/authentik.bats rewritten from compose assertions to unit-file
  contract assertions (images, Exec roles, ordering, loopback-only publish,
  pg_isready probe, secret hygiene, dispatch routing)
