## Summary by CodeRabbit

- **New Features**
- Added a new constructor for initializing validation options by
scanning assemblies.
- Introduced interfaces and a class for configuring publish-subscribe
capabilities.
- Enhanced infrastructure settings with new MassTransit configuration
options.
- Implemented notification processing context management for better
resource handling.
- Added idempotency management for domain events to prevent duplicate
processing.
  - Introduced new configuration options for local development settings.

- **Bug Fixes**
- Improved reliability of event consumption assertions in integration
tests.

- **Tests**
- Enhanced integration tests for cloud events related to dialog
operations.

- **Documentation**

 We are able to toggle some external resources in local development. This is done through the `appsettings.Development.json` file. The following settings are available:
 ```json
 "LocalDevelopment": {
-  "UseLocalDevelopmentUser": true,
-  "UseLocalDevelopmentResourceRegister": true,
-  "UseLocalDevelopmentOrganizationRegister": true,
-  "UseLocalDevelopmentNameRegister": true,
-  "UseLocalDevelopmentAltinnAuthorization": true,

 ```
 Toggling these flags will enable/disable the external resources. The `DisableAuth` flag, for example, will disable authentication in the WebAPI project. This is useful when debugging the WebAPI project in an IDE. These settings will only be respected in the `Development` environment.
