Subject: [PATCH] feat(domain): add domain enumerations

- ErrorCode: All error codes from legacy system (10001-10010)
- ProcessType: Email process types (ProcessManager, AttachmentSniffer, ZugFeRDParser)
- AuthenticationType: Authentication methods (UsernamePassword, OAuth2)
- EmailStatus: Email processing status tracking
- AttachmentStatus: Attachment validation status

These enums maintain compatibility with the legacy VB.NET system.
