Fix: WiFi association stuck bug

### 1.1.0 — 2026-03-07

New Features
==========
CO2 Air Quality Readings — The Live Data screen now displays real-time CO2 levels (in ppm) from devices equipped with air quality sensors.
WebView Flow for Unknown Devices — When a scanned device isn't a recognized thermostat type, the app now opens a WebView-based setup flow instead of showing an error. This provides forward compatibility as new device types are added.

Bug Fixes
=======
O/B Relay Occupancy Settings — Fixed an issue where the occupancy radio buttons on the O/B Relay configuration screen did not visually update when tapped.
Occupancy Mode Settings — Fixed a bug where changing the occupancy enabled/disabled toggle would incorrectly overwrite the occupancy mode setting (and vice versa).
QR Scanner License Validation — The app now alerts the user when the QR scanner license is invalid or expired, instead of silently failing.
Improved Error Messages — Device communication errors now include HTTP status codes and additional context, making it easier to diagnose connectivity issues in the field.
UI Stability — Resolved screen stuttering and input focus issues that could occur during device configuration.
