Add global exception handling middleware

Browse Source 
Introduces `GlobalExceptionHandlerMiddleware` for managing exceptions in the request pipeline, logging them, and returning JSON error responses. A new project, `DigitalData.Core.Exceptions.Middleware`, is created to house this middleware and related classes. The `GlobalExceptionHandlerOptions` class allows for custom exception registration with specific HTTP status codes, while a new `HttpResponse` record encapsulates status codes and messages for structured responses. The middleware is registered in the `DependencyInjection` class for easy integration.
