MP_WEBROOT=/mailpit prefixes every Mailpit HTTP route, including the /livez health endpoint. The container healthcheck still probed http://localhost:8025/livez, which now 404s, so Mailpit reported unhealthy; the backend depends_on it with condition: service_healthy and never started, cascading to the gateway and Caddy and failing `docker compose up --wait`. Point the healthcheck at /mailpit/livez.
