 ## [1.14.1] - 2026-10-06
 
 ### Fixed
+- **UI/UX (Componentes Genéricos)**: Refactorizado el comportamiento de `app-ou-select` para que devuelva siempre el identificador URI (`@id`) de la unidad organizativa en lugar de su ID numérico. Esto corrige varios errores críticos en cadena (como el error al mover clientes o añadir clientes a subredes de DHCP) provocados porque la API de Symfony (API Platform) requiere referencias URI (`/api/organizational_units/X`) para mapear entidades relacionales, en vez de identificadores enteros puros.
 - **DHCP Subnets**: Solucionado un error al añadir equipos a una subred donde la petición al servidor enviaba la unidad organizativa como "undefined", impidiendo listar los equipos del aula seleccionada.
