feat: add wind speed and a same-day hive-inspection verdict to weather

Temperature and rain were already tracked, but wind matters just as
much for whether it's safe/sensible to open a hive - bees get more
defensive and frames are harder to handle in wind. Adds
wind_speed_10m_max to the Open-Meteo request and a derived
inspectionSuitable flag per day (>=15C, <=1mm rain, <=25km/h wind;
null when a value is missing rather than guessing). The apiary weather
card now shows a clear "good/not good for a Durchsicht today" banner
plus wind alongside each day's forecast.
