Josh Knapp 7398f97f24 Fix notification button overflow on tablets and bump version to 2.2.0
- Fix notification button text overflow on tablet devices
- Add tablet-specific media queries for button sizing and layout
- Shorten button text from "Enable Notifications" to "Enable Alerts"
- Add responsive button constraints with min/max width and text overflow handling
- Stack queue action buttons vertically on tablets for better fit
- Bump plugin version from 2.1.0 to 2.2.0 to include all recent enhancements
