Replaced the `AsyncInitWorker` background service with the new `ConsumerInitWorker`, which introduces enhanced error handling, logging, and configurability for RabbitMQ consumer initialization.
Updated `MessagingServiceDbContext` to remove the `UseCollation` configuration for the `Username` property in the `EmailAccount` entity, ensuring compatibility with the InMemory database.
Added the `ContinueOnInitFailure` property to `RabbitMqConfiguration` to allow the application to continue running if RabbitMQ consumer initialization fails.
Cleaned up unused `using` directives in `DependencyInjection.cs` and removed the obsolete `AsyncInitWorker` class.
Enhanced RabbitMQ email processing by introducing a `SendingEmailConsumerPool` to enable the competing consumers pattern. Each consumer operates on its own channel, improving scalability and thread safety.
- Added `SendingEmailConsumerPool` to manage multiple consumers.
- Updated `DependencyInjection` to register the consumer pool.
- Refactored `SendingEmailConsumer` for better logging and error handling.
- Updated `AsyncInitWorker` to initialize the consumer pool.
- Added `ConsumerConcurrency` to RabbitMQ configuration.
- Improved error handling in `LimilabsEmailService` with detailed SMTP error messages.
Updated the `RabbitMqConfiguration` class to include:
- XML documentation for all properties, improving clarity.
- Default values for `QueueName`, `ExchangeName`, `RoutingKey`,
`DlqQueueName`, `DlqExchangeName`, and `DlqRoutingKey` to define
RabbitMQ naming conventions.
Replaced undocumented properties with documented versions to enhance
code readability and maintainability.
Reorganized the solution structure to align with a layered architecture:
- Replaced `src` folder with `core`, `infrastructure`, and `presentation`.
- Moved projects to their respective folders.
- Added `DigitalData.MessagingService.Publisher.Abstraction` project.
- Removed `DigitalData.MessagingService.Client` project.
Updated project configurations and nesting in the solution file.
Added `appsettings.Secrets.json` with RabbitMQ and email account settings:
- RabbitMQ configuration includes hostname, port, credentials, and queue/exchange details.
- Email configuration includes SMTP server details and credentials.
