feat: Add interactive D3.js wastewater dashboard for Nov 2025 data

- Updated wastewater surveillance data (334,229 samples)
- Added interactive dashboard visualizing COVID-19, Flu, and RSV trends
- 12-month trend analysis (Nov 2024 - Nov 2025)
- Current status: COVID 21.7k (↓38.5%), Flu 2.6k (↓11.2%), RSV 3.3k (↑30.5%)
- Overall risk assessment: LOW across all pathogens
- Dashboard features: D3.js charts, hover tooltips, responsive design
