feat(tests): add comprehensive test coverage for 6 modules (part 1)

- Enhanced test_upload_email.py: Added 20+ tests for email upload task (get_email_template, extract_metadata, attach_logo, prepare_recipients, send_email, upload_to_email)
- Enhanced test_api_settings.py: Added 10+ tests for settings API endpoints and models
- Created test_upload_google_drive.py: Added 25+ tests for Google Drive upload (OAuth, service account, metadata, truncation)
- Enhanced test_views_settings.py: Added 15+ tests for settings view and admin access
- Enhanced test_upload_ftp_additional.py: Added 18+ tests for FTP upload (FTPS, plaintext, directory creation, error handling)
- Enhanced test_security_headers.py: Added 12+ tests for security headers middleware
- Enhanced test_check_credentials.py: Added 15+ tests for credential checking task
- Enhanced test_views_status.py: Added 15+ tests for status dashboard and env debug views

Target: Reach ≥80% coverage for 9 modules
