{{-- v1.2 — Fase 1E-E9C (Punto 2c): botón "Cancelar en Tránsito" + modal propio, visibles solo cuando
       status='in_transit' — exige motivo, con advertencia de que la acción regresa la cantidad al
       lote origen y no se puede deshacer. Textos vía lang/es y lang/en. --}}
{{-- v1.1 — Fase 1E-E9B: reemplaza el rótulo "T-BRIDGE" por "TRÁNSITO" (Almacén en Tránsito virtual).
       Quita el filtro muerto "$zone->code !== 'T-BRIDGE'" (ese código nunca existió como zona del
       almacén destino — era un resto del diseño de lote puente). --}}
