authentik: deploy outpost as worker-role container with dial-back

In authentik 2026.8.x the proxy-provider URL space (/outpost.goauthentik.io/*)
is served by the Rust worker binary, not the server — verified live: with a
tenant-matching Host header, /if/flow/... answers 200 on the server while
/auth/caddy still 404s. The outpost instance existed in the DB but no process
ever served it, so Caddy's forward_auth subrequests hit a 404 and browsers got
authentik's own Not-Found page instead of the authentication flow.

The new unit runs the same image as server/worker with Exec=worker and flips
into outpost mode via AUTHENTIK_HOST/AUTHENTIK_INSECURE/AUTHENTIK_TOKEN (the
token is read from the DB into the host .env at deploy time; it never enters
the repo). It dials back to core over websocket and serves forward-auth on its
own 9000. Deploy handler restarts only this unit — the rest of the stack is
untouched.
