Changed

• You can now check your AirNow API key right in Settings: a new "Validate AirNow key" button on the Data Sources tab tests the key against AirNow and tells you immediately whether it works, just like the Pirate Weather key validator.

Fixed

• AirNow observations now actually reach the display. The AirNow API returns a different response format than its documentation describes (renamed camelCase fields like nowcastAQI), so every observation was discarded and AccessiWeather silently kept showing Open-Meteo's model estimate. The parser now accepts both formats, so the AQI, pollutant, and observation time match AirNow.gov.
• AirNow air quality now works for US locations saved before country detection existed. Older saved locations were silently skipped by AirNow and kept showing model-based Open-Meteo estimates — which could disagree noticeably with the official AirNow reading — even with a valid AirNow key configured.
