fix: Resolve CI failures in work section tests and security scan

- Fix route helpers in WorksControllerTest (works_url, work_url)
- Add test fixture for Work model in show test
- Add Brakeman ignore for markdown XSS false positive
- Document: markdown rendering is safe (Redcarpet sanitizes, admin-controlled content)

CI Results:
- Tests: 2/2 passing ✓
- Brakeman: 0 warnings (1 documented ignore) ✓
