Updated the `Pkcs11Options` class to rename the `DefaultApplicationName` property to `ApplicationName`, clarifying its role as a globally controlled value embedded in PDF signature metadata.
Modified `PdfDigitalSignatureService` to source `ApplicationName` directly from `Pkcs11Options`, removing client-level overrides. Updated `PdfSignatureController` to reflect this change by removing the `ApplicationName` property from `SignOptions`.
Updated `appsettings.json` and `README.md` to reflect the property name change. These changes enforce stricter configuration control, improving metadata consistency and security.
Introduced `Pkcs11Options` for configuring PKCS#11 signing workflows, including properties for library path, token selection, and signing metadata. Added `PdfSignOptionsDto` to represent signing options and `PdfSignatureCheckResultDto` with related DTOs for signature validation.
Defined `PdfSignatureCertificationLevel` enum for certification levels. Added `IPdfDigitalSignatureService` interface to support signing and validating PDF signatures. These changes enable robust and extensible handling of digital signatures.
