While looking at the WeatherFlow provider (to evaluate #4107), I noticed a few things that weren't quite right. 1. **UV index was broken for most providers in forecast/hourly views.** The templates read `uv_index`, but only the WeatherAPI provider actually wrote that key. All other providers (OpenWeatherMap, WeatherFlow, PirateWeather, etc.) use `uvIndex` - so UV was silently never displayed for them. This went unnoticed because `showUVIndex` defaults to `false` and there were no test assertions for it. Standardized everything on `uvIndex` and added test coverage. 2. **WeatherFlow didn't map precipitation for current weather.** The API provides `precip_accum_local_day` and `precip_probability`, but they weren't passed through. While adding them I also noticed the template used truthiness checks, which hid valid zero values. Fixed both. 3. **`||` vs `??` in WeatherFlow provider.** Several numeric fields used `|| null`, replacing valid `0` with `null`. Switched to `??` for correctness.
