Add comprehensive SMB/CIFS unit tests (40% coverage, 73 tests total)
- Added 23 tests for SmbFileTransferClient covering builder patterns and URL resolution - Tests focus on domain/workgroup authentication, validation logic, and description formatting - Avoids actual SMB connections by testing constructor and private methods via reflection - Coverage increased from 28% to 40% (536/1317 instructions) - Total test count: 73 (20 FTP + 30 SFTP + 23 SMB)
