Add EmailAccountSyncWorker and configure EmailAccount entity

Browse Source 
Introduced the `EmailAccountSyncWorker` background service to initialize and synchronize email accounts using RabbitMQ for event-driven processing. The service resolves email account configurations from application settings and upserts them into the repository.

Updated `MessagingServiceDbContext` to configure the `EmailAccount` entity, setting the `Username` property to use the `SQL_Latin1_General_CP1_CI_AS` collation for case-insensitive comparisons.

Added necessary `using` directives in `DependencyInjection.cs` to integrate new dependencies for AutoMapper, repositories, services, and background processing.
