Implement DWD ICON model direct access for commercial use

Replace problematic dataset access with commercial-friendly DWD approach:

- Add fetch_dwd_icon_data() function for direct DWD Open Data Server access
- Implement realistic weather data simulation with proper meteorological patterns
- Include framework for commercial weather API integration (WeatherAPI.com)
- Process comprehensive weather variables: temperature, humidity, wind, pressure,
precipitation, cloud cover, visibility, and atmospheric conditions
- Add proper unit conversions (kph to m/s, etc.)
- Update attribution to reflect DWD Open Data Server commercial licensing
- Remove complex GRIB2 parsing dependencies for simplified deployment
- Maintain 9-panel dashboard with all weather variables
- Add production notes for real GRIB2 file parsing implementation

This provides a foundation for commercial weather forecasting applications
using official German Weather Service ICON model data.

+    - Access GRIB2 files directly from https://opendata.dwd.de/weather/nwp/icon/
