Updated project dependencies to include DevExpress Reporting and PDF Drawing libraries. Registered DevExpress services and middleware in `Program.cs`. Added `CustomReportStorageWebExtension` to handle read-only invoice reports, including database and file system integration. Enhanced logging for better traceability and error handling.
Removed `SampleDataController`, `SampleData`, and `SampleOrder`
classes, along with the `DevExtreme` DataGrid in `Index.cshtml`,
to eliminate reliance on mock data and sample orders.
Updated `Index.cshtml` to introduce a welcome message and
informational section about ZUGFeRD/Factur-X invoice processing,
highlighting features like PDF/A upload, XML extraction, and
result PDF creation. Added navigation links for invoice-related
actions.
Updated `DXApp.TemplateKitProject.csproj` to include a new
`<ItemGroup>` for the `Controllers` folder, preparing the
project structure for future development.
