fix(zitadel): wire EXTERNALDOMAIN/PORT/SECURE to the generated domain

Zitadel resolves its instance from the external domain/port/scheme, so the
template's ZITADEL_EXTERNALPORT=8080 made every generated URL (OIDC issuer,
login redirects) point at http://<domain>:8080 instead of the domain served
by Traefik, ending in {"code":5,"message":"Not Found"} (#516).

- Expose ZITADEL_EXTERNALDOMAIN / ZITADEL_EXTERNALPORT / ZITADEL_EXTERNALSECURE
  as template env vars, defaulting to the generated domain over HTTP
  (port 80, secure=false) so the routed domain and Zitadel's external config
  always match; HTTPS users flip them to 443/true in the Env tab.
- Pin image to v4.16.0 (was latest) and keep the built-in login v1 via
  ZITADEL_DEFAULTINSTANCE_FEATURES_LOGINV2_REQUIRED=false so no separate
  login-v2 container is needed.
- Add the official readiness healthcheck, drop the unused /app/data volume,
  bogus SMTP env keys, published port and obsolete compose version key.

Closes #516
