feat(dashboard): add gauge, weather, and air quality widgets
- Create shared GaugeWidget with circular progress and customizable colors - Add GaugeRow for displaying multiple gauges in a responsive layout - Create WeatherWidget with temperature, condition, and details - Create AirQualityWidget with AQI levels and pollutant readings - Update DashboardContent with System Stats gauges and Environment section - Both widgets use mock data, ready for API integration 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
