Introduced IMAP functionality to enable fetching emails from an IMAP server and marking messages as seen. Updated the `EmailAccountDto` class with IMAP-related properties (`ImapServer`, `ImapPort`, `ImapUseSsl`) for configuration. Added `ReceivedEmailContext` to represent received emails and created the `IImapEmailService` interface with methods `FetchEmailsAsync` and `MarkAsSeenAsync`. Implemented the `LimilabsImapEmailService` class using Limilabs Mail.dll for IMAP operations, including connection handling, email fetching, and marking messages as seen. Added `FetchEmailsQuery` and `MarkEmailAsSeenCommand` with handlers to encapsulate IMAP logic. Updated `EmailsController` with new endpoints for fetching emails and marking messages as seen. Registered `IImapEmailService` in `DependencyInjection`. Included exception handling and logging for robust error management during IMAP operations.
