     Queue routing helper — include anywhere that renders a visit row with
     an "Open" action. Routes based on visit_type and enrollment state:

       ANC visit + AncRegistration (active)  →  maternity.anc.show
       ANC visit + NO AncRegistration        →  maternity.anc.register?patient_id=…
                                                 (guides user to enroll
                                                  instead of dumping in OPD)
       Everything else                       →  visits.show  (OPD encounter)

     Usage:
         @include('partials._queue-routing-helper')
         <a href="{{ queueOpenUrl($visit) }}">Open</a>

     The if (!function_exists(...)) guard lets this be included multiple
     times per request without redeclaration errors.
