Introduced `FetchEmailByUidQuery` to fetch a single email by its UID from an IMAP mailbox. The query includes properties for email account, UID, folder, and attachment inclusion, with a fluent method `WithUid(long uid)` to set the UID. Added `FetchEmailByUidQueryHandler` to process the query, leveraging `ISender` for account retrieval and `IImapEmailService` for email fetching. Included error handling for missing accounts and misconfigured IMAP settings. Implemented `FetchEmailByUidQueryValidator` to validate the query, ensuring the `Account` is not null, `Uid` is set and greater than 0, and `Folder` is not empty.
