fix(F6.1): unificar contexto operativo Área–Operadora (#33)

Cierra inconsistencias residuales del contexto operativo F6.1. Inventario queda ligado al Área física; la Operadora vigente se resuelve por relaciones temporales. Incluye correcciones pre-merge de búsquedas WEB, alta contextual, merge de duplicados y barreras CI/runtime. Producción permanece sin desplegar.
