feat: add full Reputation Blueprint demo page at /report-demo

Port the engine's report renderer (37 component files) into the marketing
site with anonymized data from a real 596-review analysis. Visitors see
the exact multi-page report paying customers receive — cover, executive
summary, rating dashboard, theme analysis, domain performance, trends,
critical issues, strengths, action plan, and tracking framework.

- Anonymized business data (Bistro El Sol, score 83.3)
- EN/ES language toggle in report toolbar
- Recharts: gauge, radar, scatter, donut, trend, heatmap charts
- Sticky CTA bar converting demo viewers to customers
- Demo nav link updated from anchor to /report-demo route
