fix(ci): improve link validation test robustness and reduce noise

- Fix Test Setup Validation to handle edge cases without false failures
- Remove unnecessary Cypress artifacts upload (screenshots/videos)
- Reduce verbose logging while maintaining debugging capability
- Add clear success/failure reporting with actionable messages
- Improve handling of empty test subjects and fallback scenarios

The test now only fails for genuine setup issues, not configuration
edge cases like empty subject lists or cache optimization scenarios.
