Refactor: Move GetAnnotsOfReceiver to SignatureController

The `GetAnnotsOfReceiver` method was removed from the `AnnotationController` class and moved to a newly introduced `SignatureController` class. The `SignatureController` is now a dedicated controller for handling signature-related endpoints, decorated with `[ApiController]` and `[Route("api/[controller]")]`.

The method's implementation remains largely unchanged, retaining its logic for retrieving and filtering signatures for a specific receiver. Dependency injection for `IMediator` was added to the `SignatureController` to handle the `ReadDocumentQuery`.

Additional `using` directives were added to `SignatureController.cs` to include necessary namespaces. A `TODO` comment remains in the method, indicating potential future updates.
