Fix chart sizing, model predictions, 90% intervals, and deep link district name

- Increase SVG dimensions in all 6 charts to prevent label truncation
- Fix ModelDrawsComparison: pass quadData so predictions render for three-year models
- Change error bars from 95% to 90% (legend text + SD calculation)
- Widen chart viewport: max-width 70rem vs default 60rem text width
- Fix deep link: fetch district name from API instead of showing 'Loading...'
