Refactor email services and update password handling

Browse Source 
Updated `EmailAccountDto` to use `required` properties for .NET 7+ compatibility, removing the `PasswordEncrypted` property and simplifying password handling.

Removed `IEncryptionService` dependency from `LimilabsEmailService` and `LimilabsImapEmailService`. Updated `ConnectAndAuthenticateSmtpAsync` and `OpenAsync` methods to remove password decryption logic.

Introduced `CancellationToken` support in `LimilabsImapEmailService` methods to improve cancellation handling for IMAP operations.

Added `Entities\` folder reference in `DigitalData.MessagingService.Domain.csproj`.
