- Add common SynthStationID helpers for coordinate-based providers - Use shared helper for Open-Meteo and OpenWeather station ID synthesis - Require both lat/lon when generating synthetic IDs to avoid misleading defaults - Remove unused Open-Meteo normalizer wrapper code This reduces cross-provider duplication while keeping provider-specific mapping logic explicit and readable.
