- EmailSyncWorker now fetches active email accounts from IRepository<EmailAccount>
on every polling cycle instead of reading from static options list
- Add UpsertSeedEmailAccount: on startup, seed accounts from EmailAccountsOptions
into the database via IRepository.UpsertAsync (insert or update by Username)
- Remove standalone EmailAccountSyncWorker (merged into EmailSyncWorker)
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.
Refactored `ReceivedEmailContext` to use `record` for immutability
and value-based equality. Added `SyncIntervalSeconds` to
`EmailAccountsOptions` for configuring IMAP sync intervals.
Introduced `EmailSyncWorker` as a background service for periodic
email synchronization. Registered `IMemoryCache` and integrated
caching in `LimilabsImapEmailService` to reduce redundant fetch
operations. Optimized `FetchEmailByUidAsync` to conditionally
handle attachments and improve performance.
Refactored logging and improved code readability by adopting modern
C# features like `record`, `with` expressions, and `IOptions`.
Performed general cleanup and streamlined method implementations.
