Refactored events (#621)

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.
