ABP cross-cutting behavior via Castle dynamic proxies and IAbpInterceptor. USE FOR: how validation, unit of work, authorization, auditing, feature interceptors are selected; interceptor not running; custom interceptor via Services.OnRegistered. DO NOT USE FOR: module lifecycle (define-application-modules); audit-log persistence (configure-audit-logging); feature values (manage-settings-and-features); services without interception (register-and-replace-services).
