2.0: fix crash de arranque por IDs duplicados (CloudKit)

Fatal error "Duplicate values for key" al construir diccionarios con
Dictionary(uniqueKeysWithValues:) sobre dishes/tags/slots cuyos UUID se
duplican por la sincronización CloudKit de 2.0. Se sustituyen todas las
ocurrencias por Dictionary(_, uniquingKeysWith:) para tolerar duplicados
(se conserva el primero) en lugar de abortar. La app ya no crashea al
abrir con datos duplicados; la deduplicación real queda pendiente aparte.
