fix: enforce local TailwindCSS builds, reject CDN usage

- Update verification script to check for /static/style.css (local build)
- Reject cdn.tailwindcss.com usage (violates production-ready requirement)
- Local builds are faster, have no external dependencies, and are self-contained
- Changes verification from WARNING to ERROR when CDN is detected
- Now passes all 26 checks with 0 warnings, 0 errors
