Convert TrafagSalesExporter from console app to Blazor Server app with MudBlazor UI
- Replaced console app with .NET 8 Blazor Server architecture - Added EF Core SQLite database (trafag_exporter.db) with auto-seed data - Models: HanaServer, Site, SharePointConfig, ExportSettings, ExportLog, SalesRecord - Services: HanaQueryService (with configurable dateFilter), ExcelExportService, SharePointUploadService, ExportOrchestrationService (with live status events), TimerBackgroundService (scheduled daily export) - MudBlazor UI pages: Dashboard (export status + manual trigger), Standorte (HANA server + site CRUD), Settings (SharePoint + timer config), Logs (filtered view) - SAP HANA queries unchanged (INV + CRN with exact SAP B1 table joins) - SharePoint upload via Microsoft Graph with app registration auth https://claude.ai/code/session_012heAXNMbbyxqYf2S2HrKLj
