Weather: Replace wttr.in with Open-Meteo + structured logging

- Replace wttr.in (unreachable from Docker) with Open-Meteo API
  (free, no API key, reliable) with geocoding cache
- WMO weather codes mapped to German descriptions + emoji icons
- Add [WEATHER], [NEWS], [UNRAID], [DASHBOARD] log prefixes
- Structured integration status table on startup
- Suppress noisy httpx INFO logs (services log their own summaries)
- Add logging to unraid_service (was completely silent on errors)
