Event handling: - Added unified event handling for application, system, and Wi‑Fi events. - Updated all apps to reflect event handling changes Wi-Fi: - Refactored event handling from listener interface to task & event group. - Added direct Wi‑Fi radio controls and improved event subscriptions. - Wi‑Fi screens now refresh asynchronously and handle unavailable devices more gracefully. - Enabled Wi‑Fi by default on in dts files, but radio on/off is still done by code. The main reason was reliable event subscription and consistent devicetree states. - Improved Wi‑Fi shutdown cleanup and radio-state handling. Other: - Renamed the Kernel Display app to Display.
