Moved auditing interfaces to EnvelopeGenerator.Domain.Interfaces.Auditing. Updated entity classes to reference the new namespace. Added ICreationAuditable and IUpdateAuditable interfaces to improve code organization and clarify auditing responsibilities.
Large-scale cleanup of entity and interface classes:
- Removed obsolete #if NET/NETFRAMEWORK preprocessor blocks
- Unified class/property formatting and indentation
- Standardized use of data annotations
- Improved nullable reference type handling
- Simplified interfaces (IHasEnvelope, IHasReceiver)
- Removed redundant and dead code
- No changes to business logic or data model
These changes modernize and standardize the codebase for easier maintenance and .NET compatibility.
Introduced interfaces for audit fields (AddedWhen, ChangedWhen, ChangedWho, AddedWho) and updated domain entities to implement them. Adjusted properties for consistency and nullability. Updated MappingProfile to map audit fields between DTOs and entities. Improves auditability and standardization across the domain model.
- Added `X`, `Y`, `Width`, and `Height` properties with `float` database mapping.
- Retains existing fields and database annotations.
- Prepares the entity for spatial layout handling in documents.
