fix(tests): align docker-e2e health asserts with current /api/health shape

`/api/health` is the auth-free LB probe — returns `status` + `db_schema`
only. `version` lives in `/api/version` and the richer
`services.duckdb_state` lives in `/api/health/detailed` (auth-gated).
The two e2e asserts had drifted and broke nightly on main.
