- IDataSourceAdapter mit 3 Implementierungen (HANA, SAP_GATEWAY, MANUAL_EXCEL) und DataSourceAdapterResolver ersetzen das if/else auf ConnectionKind. - SiteExportService von 338 auf 187 Zeilen reduziert: Pipeline Resolve -> Fetch -> Transform -> Excel -> Central -> SharePoint. - Page-Services auf Scoped (per Blazor-Circuit); Orchestrator bleibt Singleton fuer geteilten Export-Status.
