Dashboard visual redesign: hero, section cards, sparklines, color tiles, today bar

- Hero section with 5.5rem temperature, feels-like, live wind description
- Humidity, pressure, solar radiation, wind sparklines drawn from history data
- Today at a glance bar: today's high/low temp, rain total, peak gust
- Tile color tinting by value: temp (hot/warm/cool/cold), UV severity, wind, rain rate
- Wind cardinal direction shown in hero subtitle and secondary wind tile
- Chart lines now have subtle gradient area fill (non-dashed series only)
- Chart height increased from 200px to 240px; cards get hover shadow
- Section cards with light headers group conditions, totals, and history
