feat: Add ComplianceNFs.Infrastructure.Tests project and implement unit tests for various services

- Added ComplianceNFs.Infrastructure.Tests project to the solution.
- Implemented unit tests for AccessDbRepository, ArchivingService, AttachmentRepository, InvoiceIngestionService, MailListener, MonitorViewModel, and Worker.
- Enhanced existing tests with additional assertions and mock setups.
- Updated TODOs and roadmap documentation to reflect changes in service implementations and testing coverage.
- Modified ComplianceNFs.sln to include new test project and adjust solution properties.
