Replaced the `EmailAccountDto` class with the `EmailAccount` class across the codebase to consolidate the `EmailAccount` entity into the domain layer. Updated namespaces, method signatures, property types, and test cases to reflect this change.
Moved `EmailAccount` from `DigitalData.MessagingService.Application.Common.Dto` to `DigitalData.MessagingService.Domain.Entities`. Updated XML documentation and removed redundant project file entries. Adjusted namespaces for related queries, validators, and commands to align with the new structure.
These changes improve separation of concerns and align with domain-driven design principles.
Replaced `DigitalData.MessagingService.Abstraction` with
`DigitalData.MessagingService.Application.Common.Dto` and
`DigitalData.MessagingService.Application.Common.Dto.MailSearch`
to improve modularity and organization.
Removed the `Abstraction` project and updated all references
to use the `Application` project. Updated namespaces, `using`
directives, and dependencies across the codebase.
Refactored interfaces, commands, queries, validators, and
services to use the new DTOs. Updated RabbitMQ integration,
AutoMapper profiles, background services, and tests to align
with the new structure.
Performed general cleanup by removing redundant `using`
directives and obsolete references.
