feat(medios,secciones): application layer + handlers TDD — ADM-001 B3+B4

- IMedioRepository, ISeccionRepository interfaces - MediosQuery, SeccionesQuery common records - TipoSeccion static AllowedTipos helper - Medios: 6 use cases (Create/Update/Deactivate/Reactivate/List/GetById) with validators, handlers and DTOs - Secciones: 6 use cases mirroring Medios; Create validates MedioId active via IMedioRepository - 52 unit tests (xUnit + NSubstitute) all green; audit LogAsync asserted per mutating handler - DI registrations for all 12 handlers and validators auto-scanned via AddValidatorsFromAssemblyContaining
