      description: 'GET /api/v1/companies/companies-house/search/?q=<name>&limit=10


        Autocomplete endpoint backing the registered-company picker in MoR forms.

        Returns up to `limit` ranked, active-only candidates from Companies House.

        Returns 503 on a Companies House outage so the FE can fall back to plain

        text input rather than blocking the user. Implemented as an APIView (not a

        ViewSet `list` action) so drf-spectacular emits the response as an object

        with a `results` array rather than auto-wrapping the whole body in `[]`.'
