Subject: [PATCH] weather: fix UV index display and add WeatherFlow
precipitation (#4108)
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.
