AQI

- Added support for choosing and pinning a specific city or area for the AQI map widget, instead of only following your current location. - Improved widget setup with location search and recent-place suggestions, making it faster to reuse frequently checked locations. - Enhanced the handoff from the AQI map widget to the app, so opening the app now jumps straight to the same location on the map. - Improved the main AQI card layout on larger screens for a clearer and more balanced reading experience. - Fixed widget location search feedback for empty results, fast input changes, and network errors to make setup more reliable.
