Update the Render methods in XlsxRenderer.cs and DocxRenderer.cs to replace obsolete Export method overloads from IWorkbookFormatProvider and DocxFormatProvider. These methods now use the updated overloads that include a TimeSpan? timeout parameter. Add a new timeout setting SecurityHelper.ExportTimeout to ensure configurable timeout handling across the application. The update resolves compiler warnings (CS0618) caused by the usage of deprecated method overloads and aligns with modern practices for enhanced application performance and reliability.
