Refactored `PdfSignOptionsDto` and `PdfVisualSignatureOptionsDto`: - Converted both to immutable `record` types with non-nullable properties. - Added XML documentation comments for properties and parameters. Simplified `PdfDigitalSignatureService`: - Updated `SignPdfAsync` to enforce non-nullable `PdfSignOptionsDto`. - Removed redundant null checks and inlined `CreateSignatureBounds`. - Simplified signature appearance and image data logic. - Refactored `TryGetKeySize` to use `bool` with `out` parameter. General improvements: - Enhanced code readability and maintainability. - Reduced nullable references and enforced stricter type safety.
