Add IsReadAndConfirm to DocumentSignedNotification and derive the action, status, and final action labels from it so read-only envelopes do not report a signature.
Pass the envelope read-and-confirm mode when finalizing so the signed email matches the receiver workflow.
Changed the `Attachments` property type in `EnvelopeNotificationBase.cs` from `List` to `IReadOnlyList` to enhance immutability and thread safety. Updated the `FinalizeEnvelopeCommandHandler` in `FinalizeEnvelopeCommand.cs` to use a single-line syntax for `Attachments` initialization, improving code readability.
Introduced `EnvelopeNotificationBase` as a new base class for notifications, providing a unified structure with an abstract `GetTemplateType` method and optional attachments. Added `DocumentReceivedNotification` and updated `DocumentSignedNotification` to inherit from this base class, streamlining attachment handling and template type determination.
Refactored `IEnvelopeNotificationService` to use a generic `Notify` method, allowing for flexibility with different notification types. Updated `FinalizeEnvelopeCommandHandler` to align with the new attachment handling.
Added `EnvelopeNotificationExtensions` for converting attachments to `EmailAttachmentDto` objects and introduced `ReplacePlaceholderExtensions` for dynamic placeholder replacement in email templates using reflection. Removed outdated placeholder logic from `EnvelopeNotificationService`.
Revised FinalizeEnvelopeCommand to notify each receiver
individually instead of converting documents to Base64.
Adjusted IsActive method in EnvelopeStatusExtensions to
include EnvelopePartlySigned as active. Updated project
version to 1.7.0-beta to reflect these changes.
Replaced PKCS#11-based cryptographic operations with a new DocumentService API integration. Removed all PKCS#11-related code, configurations, and dependencies, including options, self-test status, and signing logic. Updated `FinalizeEnvelopeCommand` to include a notification service and added base64 conversion for documents. Updated `ServiceCollectionExtensions` to register the new DocumentService client. Removed outdated documentation and diagrams related to PKCS#11. Updated project files and configurations to reflect these changes and incremented the version number. Added a comment in `EnvelopeFinalizationWorker` for future RabbitMQ integration.
