git commit -m "feat: Enhance DetailModal with auto-loading and improved UX

- Add automatic data loading every 2 seconds when no chart data available
- Implement intelligent cursor-wait display for entire modal during loading
- Auto-reset to 'Alle Messwerte' (DIA0) and clear date fields on modal open
- Add Tailwind-based color system for chart lines (gray for min/max, littwin-blue for current/average)
- Improve chart line layering with background/foreground organization
- Add periodic UI updates to ensure responsive loading feedback
- Maintain manual 'Daten laden' button control alongside auto-loading
- Fix TypeScript dependencies and optimize useEffect performance"
