* EPA AQI severity categories for PM2.5-derived AQI (0-500), per meshtastic/design#54. Mirrors [Co2Severity]'s

* ppm→severity pattern, keyed on AQI value instead.

*

* The category name is a string resource (not a hardcoded literal like [Co2Severity]'s) because it is rendered next to

* the AQI value everywhere the category is shown — the category must never be conveyed by [color] alone.
