Added full implementation for CreateAnnotationCommand and its handler:
- Introduced `PSPDFKitInstantJSON` property to the command
- Injected repositories for `Signature` and `Annotation`
- Implemented query filtering for Envelope and Receiver
- Added annotation creation from parsed PSPDFKit JSON
- Created helper method `ParsePSPDFKitInstantJSON` for JSON parsing
- Added model configuration for Signature → Annotation relationship
- Removed redundant DbSet initializations from EGDbContextBase constructor
- Updated Config DbSet type from Domain.Entities.Config to Config
- Simplified using directives and removed unnecessary configuration imports
- Maintained existing trigger registration and entity configurations
- Added Annotation entity mapped to table TBSIG_DOCUMENT_RECEIVER_ELEMENT_ANNOTATION
- Included data annotations for key, required fields, and relationships
- Added conditional compilation for .NET and .NET Framework compatibility
- Removed formFieldIndex tracking and inline dictionary
- Introduced EGName class with centralized index mapping
- Updated AddFormFieldValue to resolve Y-offset using EGName.Index
- Replaced fieldName property with egName for annotations
- Changed helper methods from Function(Void) to Sub for clarity
- Added `UnstructuredAnnotations` property to handle annotations without structured IDs
- Changed default `hasStructuredID` to `False`, set to `True` only after successful parsing
- Updated `AddInstantJSONAnnotationToPDF` to process annotations directly instead of grouping by receiver
- Simplified logic for reversing annotations and applying seal positioning
- Added parsing of annotation `id` into `envelopeId`, `receiverId`, `index`, and `internalType`.
- Added validation for `id` format, ensuring it has exactly 4 parts and numeric checks for relevant fields.
- Throws `BurnAnnotationException` if `id` is null, empty, or incorrectly formatted.
- Maintains existing functionality for adding image, ink, and widget annotations.
- Methoden für Annotationen (AddInstantJSONAnnotationToPDF, AddImageAnnotation, AddInkAnnotation, AddFormFieldValue) auf Rückgabe-Typ Void umgestellt.
- Interne Try/Catch-Blöcke und das Unterdrücken von Ausnahmen in Hilfsmethoden entfernt.
- Fehlerbehandlung in BurnInstantJSONAnnotationsToPDF zentralisiert, mit Try/Catch für das Hinzufügen von Annotationen.
- Exit Select-Anweisungen für bessere Lesbarkeit in Select Case-Blöcken hinzugefügt.
- Import von DevExpress.DataProcessing ergänzt.
* Removed `dbContextOptions` parameter from `AddEnvelopeGeneratorInfrastructureServices`
* Moved `AddDbContext` registration into `Config` class with overloads for both `Action<DbContextOptionsBuilder>` and `Action<IServiceProvider, DbContextOptionsBuilder>`
* Simplified service registration flow and improved extensibility
- Wrapped `using` directives with `#if NET` and `#elif NETFRAMEWORK`
- Applied conditional inheritance for `IUserManagerDbContext` and `IMailDbContext`
- Made `EmailOut` DbSet and triggers only available in `NET` builds
- Adjusted `_logger` nullability for NET vs NETFRAMEWORK targets
- Ensured `modelBuilder.ConfigureUserManager()` only runs in NET builds
- Umschlossene Repository- und Executor-Registrierungen mit `#if NET`, um die Kompatibilität zwischen .NET und .NET Framework sicherzustellen
- Hinzufügen des Abschnitts `#elif NETFRAMEWORK` für frameworkspezifische Importe
- Verschieben der SQLExecutor- und Dapper-Typzuordnung unter bedingte Kompilierung
- Anpassen der Methodensignaturen zur Unterstützung bedingter nullbarer Parameter
- Introduced Page(Action<PdfPage>) method to apply design logic to every page in the document
- Simplified Background method by replacing per-page iteration with new Page overload
- Improved readability and maintainability by removing duplicate page loop logic
- Added `System.Linq` import to enable distinct and ordered page index selection
- Applied `ConcatMatrix` transformation once per page instead of per signature
- Improved performance and reduced redundant operations in `Background` method
